Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625332, here are decompositions:

29 + 31625303 = 31625332
71 + 31625261 = 31625332
293 + 31625039 = 31625332
353 + 31624979 = 31625332
503 + 31624829 = 31625332
569 + 31624763 = 31625332
593 + 31624739 = 31625332
659 + 31624673 = 31625332

Showing the first eight; more decompositions exist.
