Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529922, here are decompositions:

23 + 31529899 = 31529922
31 + 31529891 = 31529922
41 + 31529881 = 31529922
79 + 31529843 = 31529922
103 + 31529819 = 31529922
139 + 31529783 = 31529922
173 + 31529749 = 31529922
241 + 31529681 = 31529922

Showing the first eight; more decompositions exist.
