Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466308, here are decompositions:

17 + 31466291 = 31466308
59 + 31466249 = 31466308
101 + 31466207 = 31466308
257 + 31466051 = 31466308
479 + 31465829 = 31466308
647 + 31465661 = 31466308
659 + 31465649 = 31466308
677 + 31465631 = 31466308

Showing the first eight; more decompositions exist.
