Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466328, here are decompositions:

37 + 31466291 = 31466328
41 + 31466287 = 31466328
71 + 31466257 = 31466328
79 + 31466249 = 31466328
107 + 31466221 = 31466328
191 + 31466137 = 31466328
227 + 31466101 = 31466328
239 + 31466089 = 31466328

Showing the first eight; more decompositions exist.
