Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622998, here are decompositions:

47 + 31622951 = 31622998
59 + 31622939 = 31622998
257 + 31622741 = 31622998
269 + 31622729 = 31622998
311 + 31622687 = 31622998
419 + 31622579 = 31622998
461 + 31622537 = 31622998
479 + 31622519 = 31622998

Showing the first eight; more decompositions exist.
