Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466966, here are decompositions:

67 + 31466899 = 31466966
73 + 31466893 = 31466966
109 + 31466857 = 31466966
277 + 31466689 = 31466966
337 + 31466629 = 31466966
379 + 31466587 = 31466966
463 + 31466503 = 31466966
577 + 31466389 = 31466966

Showing the first eight; more decompositions exist.
