Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466086, here are decompositions:

23 + 31466063 = 31466086
83 + 31466003 = 31466086
107 + 31465979 = 31466086
257 + 31465829 = 31466086
359 + 31465727 = 31466086
389 + 31465697 = 31466086
467 + 31465619 = 31466086
557 + 31465529 = 31466086

Showing the first eight; more decompositions exist.
