Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484770, here are decompositions:

17 + 31484753 = 31484770
29 + 31484741 = 31484770
59 + 31484711 = 31484770
71 + 31484699 = 31484770
227 + 31484543 = 31484770
257 + 31484513 = 31484770
353 + 31484417 = 31484770
431 + 31484339 = 31484770

Showing the first eight; more decompositions exist.
