Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483486, here are decompositions:

17 + 31483469 = 31483486
29 + 31483457 = 31483486
53 + 31483433 = 31483486
173 + 31483313 = 31483486
179 + 31483307 = 31483486
257 + 31483229 = 31483486
269 + 31483217 = 31483486
317 + 31483169 = 31483486

Showing the first eight; more decompositions exist.
