Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625374, here are decompositions:

23 + 31625351 = 31625374
71 + 31625303 = 31625374
113 + 31625261 = 31625374
227 + 31625147 = 31625374
317 + 31625057 = 31625374
467 + 31624907 = 31625374
593 + 31624781 = 31625374
701 + 31624673 = 31625374

Showing the first eight; more decompositions exist.
