Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596810, here are decompositions:

13 + 31596797 = 31596810
17 + 31596793 = 31596810
41 + 31596769 = 31596810
53 + 31596757 = 31596810
59 + 31596751 = 31596810
61 + 31596749 = 31596810
67 + 31596743 = 31596810
97 + 31596713 = 31596810

Showing the first eight; more decompositions exist.
