Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466790, here are decompositions:

31 + 31466759 = 31466790
37 + 31466753 = 31466790
41 + 31466749 = 31466790
59 + 31466731 = 31466790
71 + 31466719 = 31466790
83 + 31466707 = 31466790
97 + 31466693 = 31466790
101 + 31466689 = 31466790

Showing the first eight; more decompositions exist.
