Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483490, here are decompositions:

19 + 31483471 = 31483490
37 + 31483453 = 31483490
43 + 31483447 = 31483490
61 + 31483429 = 31483490
139 + 31483351 = 31483490
163 + 31483327 = 31483490
229 + 31483261 = 31483490
277 + 31483213 = 31483490

Showing the first eight; more decompositions exist.
