Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508022, here are decompositions:

5 + 31508017 = 31508022
19 + 31508003 = 31508022
31 + 31507991 = 31508022
41 + 31507981 = 31508022
71 + 31507951 = 31508022
83 + 31507939 = 31508022
101 + 31507921 = 31508022
109 + 31507913 = 31508022

Showing the first eight; more decompositions exist.
