Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466436, here are decompositions:

47 + 31466389 = 31466436
107 + 31466329 = 31466436
109 + 31466327 = 31466436
149 + 31466287 = 31466436
173 + 31466263 = 31466436
179 + 31466257 = 31466436
229 + 31466207 = 31466436
263 + 31466173 = 31466436

Showing the first eight; more decompositions exist.
