Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596812, here are decompositions:

19 + 31596793 = 31596812
43 + 31596769 = 31596812
61 + 31596751 = 31596812
103 + 31596709 = 31596812
139 + 31596673 = 31596812
151 + 31596661 = 31596812
199 + 31596613 = 31596812
229 + 31596583 = 31596812

Showing the first eight; more decompositions exist.
