Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516196, here are decompositions:

7 + 31516189 = 31516196
13 + 31516183 = 31516196
37 + 31516159 = 31516196
43 + 31516153 = 31516196
67 + 31516129 = 31516196
73 + 31516123 = 31516196
97 + 31516099 = 31516196
109 + 31516087 = 31516196

Showing the first eight; more decompositions exist.
