Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486022, here are decompositions:

13 + 31486009 = 31486022
151 + 31485871 = 31486022
199 + 31485823 = 31486022
223 + 31485799 = 31486022
439 + 31485583 = 31486022
643 + 31485379 = 31486022
709 + 31485313 = 31486022
739 + 31485283 = 31486022

Showing the first eight; more decompositions exist.
