Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522664, here are decompositions:

7 + 31522657 = 31522664
31 + 31522633 = 31522664
67 + 31522597 = 31522664
73 + 31522591 = 31522664
223 + 31522441 = 31522664
307 + 31522357 = 31522664
337 + 31522327 = 31522664
367 + 31522297 = 31522664

Showing the first eight; more decompositions exist.
