Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466664, here are decompositions:

7 + 31466657 = 31466664
37 + 31466627 = 31466664
67 + 31466597 = 31466664
101 + 31466563 = 31466664
263 + 31466401 = 31466664
277 + 31466387 = 31466664
283 + 31466381 = 31466664
337 + 31466327 = 31466664

Showing the first eight; more decompositions exist.
