Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625260, here are decompositions:

113 + 31625147 = 31625260
281 + 31624979 = 31625260
353 + 31624907 = 31625260
431 + 31624829 = 31625260
461 + 31624799 = 31625260
479 + 31624781 = 31625260
521 + 31624739 = 31625260
587 + 31624673 = 31625260

Showing the first eight; more decompositions exist.
