Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516416, here are decompositions:

5 + 31516411 = 31516416
37 + 31516379 = 31516416
59 + 31516357 = 31516416
83 + 31516333 = 31516416
89 + 31516327 = 31516416
97 + 31516319 = 31516416
163 + 31516253 = 31516416
179 + 31516237 = 31516416

Showing the first eight; more decompositions exist.
