Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483374, here are decompositions:

5 + 31483369 = 31483374
23 + 31483351 = 31483374
47 + 31483327 = 31483374
61 + 31483313 = 31483374
67 + 31483307 = 31483374
113 + 31483261 = 31483374
137 + 31483237 = 31483374
157 + 31483217 = 31483374

Showing the first eight; more decompositions exist.
