Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607416, here are decompositions:

17 + 31607399 = 31607416
53 + 31607363 = 31607416
59 + 31607357 = 31607416
89 + 31607327 = 31607416
107 + 31607309 = 31607416
179 + 31607237 = 31607416
263 + 31607153 = 31607416
419 + 31606997 = 31607416

Showing the first eight; more decompositions exist.
