Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522088, here are decompositions:

67 + 31522021 = 31522088
97 + 31521991 = 31522088
109 + 31521979 = 31522088
349 + 31521739 = 31522088
421 + 31521667 = 31522088
439 + 31521649 = 31522088
547 + 31521541 = 31522088
607 + 31521481 = 31522088

Showing the first eight; more decompositions exist.
