Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484826, here are decompositions:

5 + 31484821 = 31484826
29 + 31484797 = 31484826
73 + 31484753 = 31484826
127 + 31484699 = 31484826
179 + 31484647 = 31484826
199 + 31484627 = 31484826
257 + 31484569 = 31484826
283 + 31484543 = 31484826

Showing the first eight; more decompositions exist.
