Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466230, here are decompositions:

23 + 31466207 = 31466230
167 + 31466063 = 31466230
179 + 31466051 = 31466230
227 + 31466003 = 31466230
251 + 31465979 = 31466230
401 + 31465829 = 31466230
449 + 31465781 = 31466230
503 + 31465727 = 31466230

Showing the first eight; more decompositions exist.
