Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466262, here are decompositions:

5 + 31466257 = 31466262
11 + 31466251 = 31466262
13 + 31466249 = 31466262
29 + 31466233 = 31466262
41 + 31466221 = 31466262
89 + 31466173 = 31466262
173 + 31466089 = 31466262
199 + 31466063 = 31466262

Showing the first eight; more decompositions exist.
