Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522822, here are decompositions:

239 + 31522583 = 31522822
269 + 31522553 = 31522822
281 + 31522541 = 31522822
293 + 31522529 = 31522822
389 + 31522433 = 31522822
449 + 31522373 = 31522822
491 + 31522331 = 31522822
509 + 31522313 = 31522822

Showing the first eight; more decompositions exist.
