Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466214, here are decompositions:

7 + 31466207 = 31466214
41 + 31466173 = 31466214
71 + 31466143 = 31466214
107 + 31466107 = 31466214
113 + 31466101 = 31466214
151 + 31466063 = 31466214
163 + 31466051 = 31466214
211 + 31466003 = 31466214

Showing the first eight; more decompositions exist.
