Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466122, here are decompositions:

3 + 31466119 = 31466122
59 + 31466063 = 31466122
71 + 31466051 = 31466122
293 + 31465829 = 31466122
449 + 31465673 = 31466122
461 + 31465661 = 31466122
491 + 31465631 = 31466122
503 + 31465619 = 31466122

Showing the first eight; more decompositions exist.
