Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483380, here are decompositions:

11 + 31483369 = 31483380
29 + 31483351 = 31483380
53 + 31483327 = 31483380
67 + 31483313 = 31483380
73 + 31483307 = 31483380
151 + 31483229 = 31483380
163 + 31483217 = 31483380
167 + 31483213 = 31483380

Showing the first eight; more decompositions exist.
