Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596982, here are decompositions:

5 + 31596977 = 31596982
59 + 31596923 = 31596982
83 + 31596899 = 31596982
101 + 31596881 = 31596982
233 + 31596749 = 31596982
239 + 31596743 = 31596982
269 + 31596713 = 31596982
311 + 31596671 = 31596982

Showing the first eight; more decompositions exist.
