Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483480, here are decompositions:

11 + 31483469 = 31483480
23 + 31483457 = 31483480
47 + 31483433 = 31483480
89 + 31483391 = 31483480
167 + 31483313 = 31483480
173 + 31483307 = 31483480
251 + 31483229 = 31483480
263 + 31483217 = 31483480

Showing the first eight; more decompositions exist.
