Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508934, here are decompositions:

13 + 31508921 = 31508934
47 + 31508887 = 31508934
71 + 31508863 = 31508934
251 + 31508683 = 31508934
257 + 31508677 = 31508934
263 + 31508671 = 31508934
277 + 31508657 = 31508934
283 + 31508651 = 31508934

Showing the first eight; more decompositions exist.
