Thanks. In the worst case scenario I will be double-checking your work, which shouldn't hurt anyone. I don't expect that to take too long after sieving.

I will reserve all y for 13001 <= x <= 15000. I will also double-check from x=12501 to x = 13000.

I will do all I can to avoid stepping on the toes of the other search for primes of this form...

Sophie-Germain primes are numbers were p and 2p-1 are prime. For this sieve p = k*2^n+1 and it sieves for a fixed n and range of k since sieving that form does not require a discrete log.

For SGS, wouldn't it be faster to sieve with fixed n and variable k? I can't imagine that it would be hard to implement such a sieve in the mtsieve framework.
