Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484748, here are decompositions:

7 + 31484741 = 31484748
37 + 31484711 = 31484748
101 + 31484647 = 31484748
131 + 31484617 = 31484748
179 + 31484569 = 31484748
331 + 31484417 = 31484748
389 + 31484359 = 31484748
409 + 31484339 = 31484748

Showing the first eight; more decompositions exist.
