Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466130, here are decompositions:

11 + 31466119 = 31466130
23 + 31466107 = 31466130
29 + 31466101 = 31466130
41 + 31466089 = 31466130
67 + 31466063 = 31466130
79 + 31466051 = 31466130
127 + 31466003 = 31466130
131 + 31465999 = 31466130

Showing the first eight; more decompositions exist.
