Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596818, here are decompositions:

61 + 31596757 = 31596818
67 + 31596751 = 31596818
109 + 31596709 = 31596818
139 + 31596679 = 31596818
157 + 31596661 = 31596818
181 + 31596637 = 31596818
277 + 31596541 = 31596818
307 + 31596511 = 31596818

Showing the first eight; more decompositions exist.
