Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625266, here are decompositions:

3 + 31625263 = 31625266
5 + 31625261 = 31625266
227 + 31625039 = 31625266
359 + 31624907 = 31625266
467 + 31624799 = 31625266
503 + 31624763 = 31625266
593 + 31624673 = 31625266
653 + 31624613 = 31625266

Showing the first eight; more decompositions exist.
