Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466340, here are decompositions:

11 + 31466329 = 31466340
13 + 31466327 = 31466340
53 + 31466287 = 31466340
83 + 31466257 = 31466340
89 + 31466251 = 31466340
107 + 31466233 = 31466340
167 + 31466173 = 31466340
197 + 31466143 = 31466340

Showing the first eight; more decompositions exist.
