Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508922, here are decompositions:

59 + 31508863 = 31508922
79 + 31508843 = 31508922
131 + 31508791 = 31508922
191 + 31508731 = 31508922
239 + 31508683 = 31508922
241 + 31508681 = 31508922
251 + 31508671 = 31508922
271 + 31508651 = 31508922

Showing the first eight; more decompositions exist.
