Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596966, here are decompositions:

17 + 31596949 = 31596966
43 + 31596923 = 31596966
53 + 31596913 = 31596966
59 + 31596907 = 31596966
67 + 31596899 = 31596966
83 + 31596883 = 31596966
109 + 31596857 = 31596966
127 + 31596839 = 31596966

Showing the first eight; more decompositions exist.
