Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596816, here are decompositions:

19 + 31596797 = 31596816
23 + 31596793 = 31596816
47 + 31596769 = 31596816
59 + 31596757 = 31596816
67 + 31596749 = 31596816
73 + 31596743 = 31596816
103 + 31596713 = 31596816
107 + 31596709 = 31596816

Showing the first eight; more decompositions exist.
