Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625126, here are decompositions:

67 + 31625059 = 31625126
199 + 31624927 = 31625126
277 + 31624849 = 31625126
373 + 31624753 = 31625126
409 + 31624717 = 31625126
487 + 31624639 = 31625126
499 + 31624627 = 31625126
619 + 31624507 = 31625126

Showing the first eight; more decompositions exist.
