Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484812, here are decompositions:

11 + 31484801 = 31484812
41 + 31484771 = 31484812
59 + 31484753 = 31484812
71 + 31484741 = 31484812
101 + 31484711 = 31484812
113 + 31484699 = 31484812
269 + 31484543 = 31484812
449 + 31484363 = 31484812

Showing the first eight; more decompositions exist.
