Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522166, here are decompositions:

37 + 31522129 = 31522166
283 + 31521883 = 31522166
337 + 31521829 = 31522166
373 + 31521793 = 31522166
499 + 31521667 = 31522166
523 + 31521643 = 31522166
607 + 31521559 = 31522166
727 + 31521439 = 31522166

Showing the first eight; more decompositions exist.
