Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596804, here are decompositions:

7 + 31596797 = 31596804
11 + 31596793 = 31596804
47 + 31596757 = 31596804
53 + 31596751 = 31596804
61 + 31596743 = 31596804
97 + 31596707 = 31596804
131 + 31596673 = 31596804
167 + 31596637 = 31596804

Showing the first eight; more decompositions exist.
