Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667810, here are decompositions:

13 + 8667797 = 8667810
17 + 8667793 = 8667810
83 + 8667727 = 8667810
89 + 8667721 = 8667810
103 + 8667707 = 8667810
113 + 8667697 = 8667810
149 + 8667661 = 8667810
157 + 8667653 = 8667810

Showing the first eight; more decompositions exist.
