Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667816, here are decompositions:

7 + 8667809 = 8667816
19 + 8667797 = 8667816
23 + 8667793 = 8667816
83 + 8667733 = 8667816
89 + 8667727 = 8667816
109 + 8667707 = 8667816
127 + 8667689 = 8667816
139 + 8667677 = 8667816

Showing the first eight; more decompositions exist.
