Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667812, here are decompositions:

3 + 8667809 = 8667812
19 + 8667793 = 8667812
79 + 8667733 = 8667812
151 + 8667661 = 8667812
199 + 8667613 = 8667812
211 + 8667601 = 8667812
409 + 8667403 = 8667812
463 + 8667349 = 8667812

Showing the first eight; more decompositions exist.
