Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530022, here are decompositions:

5 + 31530017 = 31530022
53 + 31529969 = 31530022
89 + 31529933 = 31530022
131 + 31529891 = 31530022
179 + 31529843 = 31530022
239 + 31529783 = 31530022
353 + 31529669 = 31530022
701 + 31529321 = 31530022

Showing the first eight; more decompositions exist.
