Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522118, here are decompositions:

97 + 31522021 = 31522118
127 + 31521991 = 31522118
139 + 31521979 = 31522118
379 + 31521739 = 31522118
547 + 31521571 = 31522118
577 + 31521541 = 31522118
619 + 31521499 = 31522118
709 + 31521409 = 31522118

Showing the first eight; more decompositions exist.
