Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508952, here are decompositions:

5 + 31508947 = 31508952
31 + 31508921 = 31508952
89 + 31508863 = 31508952
109 + 31508843 = 31508952
239 + 31508713 = 31508952
269 + 31508683 = 31508952
271 + 31508681 = 31508952
281 + 31508671 = 31508952

Showing the first eight; more decompositions exist.
