Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483456, here are decompositions:

3 + 31483453 = 31483456
23 + 31483433 = 31483456
149 + 31483307 = 31483456
227 + 31483229 = 31483456
239 + 31483217 = 31483456
293 + 31483163 = 31483456
359 + 31483097 = 31483456
479 + 31482977 = 31483456

Showing the first eight; more decompositions exist.
