Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484782, here are decompositions:

5 + 31484777 = 31484782
11 + 31484771 = 31484782
29 + 31484753 = 31484782
41 + 31484741 = 31484782
71 + 31484711 = 31484782
83 + 31484699 = 31484782
239 + 31484543 = 31484782
269 + 31484513 = 31484782

Showing the first eight; more decompositions exist.
