Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522708, here are decompositions:

167 + 31522541 = 31522708
179 + 31522529 = 31522708
257 + 31522451 = 31522708
431 + 31522277 = 31522708
461 + 31522247 = 31522708
467 + 31522241 = 31522708
479 + 31522229 = 31522708
617 + 31522091 = 31522708

Showing the first eight; more decompositions exist.
