Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466826, here are decompositions:

5 + 31466821 = 31466826
67 + 31466759 = 31466826
73 + 31466753 = 31466826
107 + 31466719 = 31466826
113 + 31466713 = 31466826
137 + 31466689 = 31466826
197 + 31466629 = 31466826
199 + 31466627 = 31466826

Showing the first eight; more decompositions exist.
