Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625362, here are decompositions:

11 + 31625351 = 31625362
59 + 31625303 = 31625362
101 + 31625261 = 31625362
383 + 31624979 = 31625362
563 + 31624799 = 31625362
599 + 31624763 = 31625362
701 + 31624661 = 31625362
719 + 31624643 = 31625362

Showing the first eight; more decompositions exist.
