Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466226, here are decompositions:

5 + 31466221 = 31466226
19 + 31466207 = 31466226
53 + 31466173 = 31466226
83 + 31466143 = 31466226
89 + 31466137 = 31466226
107 + 31466119 = 31466226
137 + 31466089 = 31466226
163 + 31466063 = 31466226

Showing the first eight; more decompositions exist.
