Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625242, here are decompositions:

263 + 31624979 = 31625242
443 + 31624799 = 31625242
461 + 31624781 = 31625242
479 + 31624763 = 31625242
503 + 31624739 = 31625242
569 + 31624673 = 31625242
599 + 31624643 = 31625242
683 + 31624559 = 31625242

Showing the first eight; more decompositions exist.
