Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466252, here are decompositions:

3 + 31466249 = 31466252
19 + 31466233 = 31466252
31 + 31466221 = 31466252
79 + 31466173 = 31466252
109 + 31466143 = 31466252
151 + 31466101 = 31466252
163 + 31466089 = 31466252
199 + 31466053 = 31466252

Showing the first eight; more decompositions exist.
