Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466316, here are decompositions:

29 + 31466287 = 31466316
53 + 31466263 = 31466316
59 + 31466257 = 31466316
67 + 31466249 = 31466316
83 + 31466233 = 31466316
109 + 31466207 = 31466316
173 + 31466143 = 31466316
179 + 31466137 = 31466316

Showing the first eight; more decompositions exist.
