Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522486, here are decompositions:

53 + 31522433 = 31522486
113 + 31522373 = 31522486
173 + 31522313 = 31522486
239 + 31522247 = 31522486
257 + 31522229 = 31522486
383 + 31522103 = 31522486
467 + 31522019 = 31522486
509 + 31521977 = 31522486

Showing the first eight; more decompositions exist.
