Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483826, here are decompositions:

7 + 31483819 = 31483826
19 + 31483807 = 31483826
37 + 31483789 = 31483826
67 + 31483759 = 31483826
103 + 31483723 = 31483826
163 + 31483663 = 31483826
229 + 31483597 = 31483826
277 + 31483549 = 31483826

Showing the first eight; more decompositions exist.
