Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596608, here are decompositions:

37 + 31596571 = 31596608
67 + 31596541 = 31596608
97 + 31596511 = 31596608
229 + 31596379 = 31596608
457 + 31596151 = 31596608
487 + 31596121 = 31596608
541 + 31596067 = 31596608
601 + 31596007 = 31596608

Showing the first eight; more decompositions exist.
