Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625224, here are decompositions:

167 + 31625057 = 31625224
317 + 31624907 = 31625224
443 + 31624781 = 31625224
461 + 31624763 = 31625224
563 + 31624661 = 31625224
593 + 31624631 = 31625224
677 + 31624547 = 31625224
857 + 31624367 = 31625224

Showing the first eight; more decompositions exist.
