Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596948, here are decompositions:

41 + 31596907 = 31596948
59 + 31596889 = 31596948
67 + 31596881 = 31596948
101 + 31596847 = 31596948
109 + 31596839 = 31596948
127 + 31596821 = 31596948
151 + 31596797 = 31596948
179 + 31596769 = 31596948

Showing the first eight; more decompositions exist.
