Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466712, here are decompositions:

5 + 31466707 = 31466712
19 + 31466693 = 31466712
23 + 31466689 = 31466712
41 + 31466671 = 31466712
83 + 31466629 = 31466712
149 + 31466563 = 31466712
163 + 31466549 = 31466712
311 + 31466401 = 31466712

Showing the first eight; more decompositions exist.
