Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522082, here are decompositions:

61 + 31522021 = 31522082
103 + 31521979 = 31522082
199 + 31521883 = 31522082
409 + 31521673 = 31522082
433 + 31521649 = 31522082
439 + 31521643 = 31522082
523 + 31521559 = 31522082
541 + 31521541 = 31522082

Showing the first eight; more decompositions exist.
