Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466730, here are decompositions:

11 + 31466719 = 31466730
17 + 31466713 = 31466730
23 + 31466707 = 31466730
37 + 31466693 = 31466730
41 + 31466689 = 31466730
59 + 31466671 = 31466730
73 + 31466657 = 31466730
101 + 31466629 = 31466730

Showing the first eight; more decompositions exist.
