Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625366, here are decompositions:

103 + 31625263 = 31625366
307 + 31625059 = 31625366
439 + 31624927 = 31625366
613 + 31624753 = 31625366
727 + 31624639 = 31625366
739 + 31624627 = 31625366
769 + 31624597 = 31625366
859 + 31624507 = 31625366

Showing the first eight; more decompositions exist.
