Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596956, here are decompositions:

7 + 31596949 = 31596956
43 + 31596913 = 31596956
67 + 31596889 = 31596956
73 + 31596883 = 31596956
109 + 31596847 = 31596956
163 + 31596793 = 31596956
199 + 31596757 = 31596956
277 + 31596679 = 31596956

Showing the first eight; more decompositions exist.
