Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516410, here are decompositions:

31 + 31516379 = 31516410
53 + 31516357 = 31516410
83 + 31516327 = 31516410
113 + 31516297 = 31516410
157 + 31516253 = 31516410
173 + 31516237 = 31516410
227 + 31516183 = 31516410
251 + 31516159 = 31516410

Showing the first eight; more decompositions exist.
