Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522756, here are decompositions:

173 + 31522583 = 31522756
227 + 31522529 = 31522756
233 + 31522523 = 31522756
263 + 31522493 = 31522756
383 + 31522373 = 31522756
443 + 31522313 = 31522756
479 + 31522277 = 31522756
509 + 31522247 = 31522756

Showing the first eight; more decompositions exist.
