Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484794, here are decompositions:

17 + 31484777 = 31484794
23 + 31484771 = 31484794
41 + 31484753 = 31484794
53 + 31484741 = 31484794
83 + 31484711 = 31484794
167 + 31484627 = 31484794
251 + 31484543 = 31484794
281 + 31484513 = 31484794

Showing the first eight; more decompositions exist.
