Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467018, here are decompositions:

7 + 31467011 = 31467018
19 + 31466999 = 31467018
29 + 31466989 = 31467018
41 + 31466977 = 31467018
67 + 31466951 = 31467018
151 + 31466867 = 31467018
197 + 31466821 = 31467018
227 + 31466791 = 31467018

Showing the first eight; more decompositions exist.
