Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484422, here are decompositions:

5 + 31484417 = 31484422
59 + 31484363 = 31484422
83 + 31484339 = 31484422
293 + 31484129 = 31484422
353 + 31484069 = 31484422
443 + 31483979 = 31484422
503 + 31483919 = 31484422
509 + 31483913 = 31484422

Showing the first eight; more decompositions exist.
