Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596984, here are decompositions:

7 + 31596977 = 31596984
61 + 31596923 = 31596984
71 + 31596913 = 31596984
101 + 31596883 = 31596984
103 + 31596881 = 31596984
127 + 31596857 = 31596984
137 + 31596847 = 31596984
163 + 31596821 = 31596984

Showing the first eight; more decompositions exist.
