All mersenne numbers, prime exponent or not, are 3 (mod 4), as they end in 11 in binary.

Why would you do that? It will take a lot of time to build that list, and it will find a lot of unneeded composite factors which you need to factor later to find the real prime factors.

Bingo!

You still get 4 classes to test for factors; to reduce more the percentages, you need new primes in the modulo.
