Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596870, here are decompositions:

13 + 31596857 = 31596870
23 + 31596847 = 31596870
31 + 31596839 = 31596870
73 + 31596797 = 31596870
101 + 31596769 = 31596870
113 + 31596757 = 31596870
127 + 31596743 = 31596870
157 + 31596713 = 31596870

Showing the first eight; more decompositions exist.
