Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466518, here are decompositions:

131 + 31466387 = 31466518
137 + 31466381 = 31466518
191 + 31466327 = 31466518
227 + 31466291 = 31466518
269 + 31466249 = 31466518
311 + 31466207 = 31466518
467 + 31466051 = 31466518
761 + 31465757 = 31466518

Showing the first eight; more decompositions exist.
