Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484764, here are decompositions:

11 + 31484753 = 31484764
23 + 31484741 = 31484764
53 + 31484711 = 31484764
137 + 31484627 = 31484764
251 + 31484513 = 31484764
347 + 31484417 = 31484764
401 + 31484363 = 31484764
461 + 31484303 = 31484764

Showing the first eight; more decompositions exist.
