This is for the number of bits the Mersenne number has been trial factored
to. I.E. your last number was factored to 2^63.
the reason that it reported a problem was that the exponent was composite.
This means that the corisponding Mersenne number is composite, thus
we only check prime exponents.
The number 5014947=3*7*47*5081. Thus 2^3-1, 2^7-1, 2^47-1, and 2^5081-1
all divide 2^5014947-1 (though they do not factor it completely!).
