Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625122, here are decompositions:

83 + 31625039 = 31625122
293 + 31624829 = 31625122
359 + 31624763 = 31625122
383 + 31624739 = 31625122
449 + 31624673 = 31625122
461 + 31624661 = 31625122
479 + 31624643 = 31625122
491 + 31624631 = 31625122

Showing the first eight; more decompositions exist.
