Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466726, here are decompositions:

7 + 31466719 = 31466726
13 + 31466713 = 31466726
19 + 31466707 = 31466726
37 + 31466689 = 31466726
97 + 31466629 = 31466726
139 + 31466587 = 31466726
163 + 31466563 = 31466726
223 + 31466503 = 31466726

Showing the first eight; more decompositions exist.
