Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508376, here are decompositions:

13 + 31508363 = 31508376
17 + 31508359 = 31508376
47 + 31508329 = 31508376
89 + 31508287 = 31508376
149 + 31508227 = 31508376
173 + 31508203 = 31508376
197 + 31508179 = 31508376
199 + 31508177 = 31508376

Showing the first eight; more decompositions exist.
