Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466666, here are decompositions:

37 + 31466629 = 31466666
79 + 31466587 = 31466666
103 + 31466563 = 31466666
163 + 31466503 = 31466666
277 + 31466389 = 31466666
337 + 31466329 = 31466666
379 + 31466287 = 31466666
409 + 31466257 = 31466666

Showing the first eight; more decompositions exist.
