Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522016, here are decompositions:

3 + 31522013 = 31522016
37 + 31521979 = 31522016
223 + 31521793 = 31522016
277 + 31521739 = 31522016
349 + 31521667 = 31522016
367 + 31521649 = 31522016
373 + 31521643 = 31522016
457 + 31521559 = 31522016

Showing the first eight; more decompositions exist.
