Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466374, here are decompositions:

47 + 31466327 = 31466374
83 + 31466291 = 31466374
167 + 31466207 = 31466374
311 + 31466063 = 31466374
593 + 31465781 = 31466374
617 + 31465757 = 31466374
647 + 31465727 = 31466374
677 + 31465697 = 31466374

Showing the first eight; more decompositions exist.
