Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483474, here are decompositions:

3 + 31483471 = 31483474
5 + 31483469 = 31483474
17 + 31483457 = 31483474
41 + 31483433 = 31483474
83 + 31483391 = 31483474
167 + 31483307 = 31483474
257 + 31483217 = 31483474
311 + 31483163 = 31483474

Showing the first eight; more decompositions exist.
