Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516226, here are decompositions:

37 + 31516189 = 31516226
43 + 31516183 = 31516226
67 + 31516159 = 31516226
73 + 31516153 = 31516226
97 + 31516129 = 31516226
103 + 31516123 = 31516226
127 + 31516099 = 31516226
139 + 31516087 = 31516226

Showing the first eight; more decompositions exist.
