Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537022, here are decompositions:

19 + 31537003 = 31537022
31 + 31536991 = 31537022
79 + 31536943 = 31537022
151 + 31536871 = 31537022
193 + 31536829 = 31537022
199 + 31536823 = 31537022
229 + 31536793 = 31537022
409 + 31536613 = 31537022

Showing the first eight; more decompositions exist.
