Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484674, here are decompositions:

47 + 31484627 = 31484674
131 + 31484543 = 31484674
257 + 31484417 = 31484674
311 + 31484363 = 31484674
467 + 31484207 = 31484674
593 + 31484081 = 31484674
761 + 31483913 = 31484674
797 + 31483877 = 31484674

Showing the first eight; more decompositions exist.
