Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525262, here are decompositions:

19 + 31525243 = 31525262
61 + 31525201 = 31525262
79 + 31525183 = 31525262
271 + 31524991 = 31525262
499 + 31524763 = 31525262
541 + 31524721 = 31525262
619 + 31524643 = 31525262
739 + 31524523 = 31525262

Showing the first eight; more decompositions exist.
