Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464108, here are decompositions:

29 + 31464079 = 31464108
41 + 31464067 = 31464108
47 + 31464061 = 31464108
61 + 31464047 = 31464108
107 + 31464001 = 31464108
149 + 31463959 = 31464108
167 + 31463941 = 31464108
197 + 31463911 = 31464108

Showing the first eight; more decompositions exist.
