Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484758, here are decompositions:

5 + 31484753 = 31484758
17 + 31484741 = 31484758
47 + 31484711 = 31484758
59 + 31484699 = 31484758
131 + 31484627 = 31484758
419 + 31484339 = 31484758
491 + 31484267 = 31484758
521 + 31484237 = 31484758

Showing the first eight; more decompositions exist.
