Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466670, here are decompositions:

13 + 31466657 = 31466670
41 + 31466629 = 31466670
43 + 31466627 = 31466670
73 + 31466597 = 31466670
83 + 31466587 = 31466670
107 + 31466563 = 31466670
167 + 31466503 = 31466670
269 + 31466401 = 31466670

Showing the first eight; more decompositions exist.
