Here is a slightly different version which is better when you need more dynamic
layers.
\definelayer
[pagenumber][width=\overlaywidth,height=\overlayheight,preset=middle]
\defineoverlay[pagenumber][\texsetup{layer}]
\startsetups layer
\setlayer[pagenumber]{Page \pagenumber}
\tightlayer[pagenumber]
\stopsetups
\setupbackgrounds[page][background=pagenumber]
\starttext
\dorecurse{4}{\page[empty]}
\stoptext
