Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466508, here are decompositions:

5 + 31466503 = 31466508
107 + 31466401 = 31466508
127 + 31466381 = 31466508
167 + 31466341 = 31466508
179 + 31466329 = 31466508
181 + 31466327 = 31466508
251 + 31466257 = 31466508
257 + 31466251 = 31466508

Showing the first eight; more decompositions exist.
