Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516134, here are decompositions:

5 + 31516129 = 31516134
11 + 31516123 = 31516134
31 + 31516103 = 31516134
47 + 31516087 = 31516134
53 + 31516081 = 31516134
73 + 31516061 = 31516134
107 + 31516027 = 31516134
113 + 31516021 = 31516134

Showing the first eight; more decompositions exist.
