Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516316, here are decompositions:

19 + 31516297 = 31516316
79 + 31516237 = 31516316
127 + 31516189 = 31516316
157 + 31516159 = 31516316
163 + 31516153 = 31516316
193 + 31516123 = 31516316
229 + 31516087 = 31516316
367 + 31515949 = 31516316

Showing the first eight; more decompositions exist.
