Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484784, here are decompositions:

7 + 31484777 = 31484784
13 + 31484771 = 31484784
31 + 31484753 = 31484784
43 + 31484741 = 31484784
73 + 31484711 = 31484784
137 + 31484647 = 31484784
157 + 31484627 = 31484784
167 + 31484617 = 31484784

Showing the first eight; more decompositions exist.
