Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500262, here are decompositions:

41 + 31500221 = 31500262
113 + 31500149 = 31500262
149 + 31500113 = 31500262
179 + 31500083 = 31500262
239 + 31500023 = 31500262
419 + 31499843 = 31500262
641 + 31499621 = 31500262
701 + 31499561 = 31500262

Showing the first eight; more decompositions exist.
