Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466858, here are decompositions:

37 + 31466821 = 31466858
67 + 31466791 = 31466858
109 + 31466749 = 31466858
127 + 31466731 = 31466858
139 + 31466719 = 31466858
151 + 31466707 = 31466858
229 + 31466629 = 31466858
271 + 31466587 = 31466858

Showing the first eight; more decompositions exist.
