Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466766, here are decompositions:

7 + 31466759 = 31466766
13 + 31466753 = 31466766
17 + 31466749 = 31466766
47 + 31466719 = 31466766
53 + 31466713 = 31466766
59 + 31466707 = 31466766
73 + 31466693 = 31466766
109 + 31466657 = 31466766

Showing the first eight; more decompositions exist.
