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 less than 100,000 decimal digits. If anything I will be double-checking their work. They will likely complete their search before I start testing the range they are working on.
