Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522628, here are decompositions:

31 + 31522597 = 31522628
37 + 31522591 = 31522628
79 + 31522549 = 31522628
271 + 31522357 = 31522628
331 + 31522297 = 31522628
409 + 31522219 = 31522628
421 + 31522207 = 31522628
499 + 31522129 = 31522628

Showing the first eight; more decompositions exist.
