Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466906, here are decompositions:

7 + 31466899 = 31466906
13 + 31466893 = 31466906
157 + 31466749 = 31466906
193 + 31466713 = 31466906
199 + 31466707 = 31466906
277 + 31466629 = 31466906
577 + 31466329 = 31466906
619 + 31466287 = 31466906

Showing the first eight; more decompositions exist.
