Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625356, here are decompositions:

5 + 31625351 = 31625356
53 + 31625303 = 31625356
317 + 31625039 = 31625356
449 + 31624907 = 31625356
557 + 31624799 = 31625356
593 + 31624763 = 31625356
617 + 31624739 = 31625356
683 + 31624673 = 31625356

Showing the first eight; more decompositions exist.
