Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522712, here are decompositions:

19 + 31522693 = 31522712
43 + 31522669 = 31522712
79 + 31522633 = 31522712
163 + 31522549 = 31522712
271 + 31522441 = 31522712
349 + 31522363 = 31522712
373 + 31522339 = 31522712
691 + 31522021 = 31522712

Showing the first eight; more decompositions exist.
