Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522508, here are decompositions:

67 + 31522441 = 31522508
97 + 31522411 = 31522508
151 + 31522357 = 31522508
181 + 31522327 = 31522508
211 + 31522297 = 31522508
379 + 31522129 = 31522508
487 + 31522021 = 31522508
769 + 31521739 = 31522508

Showing the first eight; more decompositions exist.
