A couple of important questions are; RC or fiber based paper, and color
or B&W. An old fiber based B&W print can take a very long time in
water, with no ill effects.
The fiber based paper will allow the water to permeate the emulsion and
soften it and probably cause the bond with the glass to release.
RC paper will only allow water to get to the emulsion from the edges,
and the emulsion may well peel from the plastic coated paper substrate
rather than the glass.
B&W paper was expected to spend a fair amount of time in a water wash,
with no ill effects. Color not so much.
I don't know how much this helps, but I'd expect good results more
likely from soaking in water if it's a B&W print on fiber based paper.

Thanks Paul. Yes, optical, not inkjet. That is what I meant to imply by
“commercial” but I wasn’t clear.

I'm assuming it's an optical print. If it's an ink jet print it's probably
toast.

You can definitely give it a few hours. I've washed prints that long. I would
agitate gently every 30 minutes or so.

The print in question is an 11x14 color commercially printed favorite of mine -
taken with P645 one early foggy morning in 1999…
So we had a flood. The garage had water up to 26.5 inches. It would have taken
27.5 inches for the water from the river to begin flowing on into the house, so
that was the good news.
But among other items not removed from the garage before the water rose was a
trunk containing many posters, photo prints, commercial prints (e.g. my
collection of Byte Magazine cover artwork).
Now that I have cleaned, repaired, or discarded everything else from the
garage, it is time to start salvaging the artwork.
Some of the prints have been easy. Soak, wash gently, rinse, squeegee, and
place in a blotter book. Seems to be working. But THE print in question is
about 80% stuck to the glass from the frame. Yes it was matted, but either the
mat was too flimsy or it softened too much due to the soaking it received in
the flood. So the print is stuck to the glass.
I have the glass + print soaking in a large trey. I think/hope eventually the
print will float off.
So here (at last) is the question: how long can I leave a photographic print to
soak? Is there some point at which the emulsion will begin to decompose? I
would rather let it be for a few hours rather than trying to peel it off the
glass, but I don’t know how long I can wait before I cause more damage.
I may or may not be able to find the negative from which I printed, and I would
kinda like to salvage and retain the original print…
Thanks for any suggestions!
