Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667876, here are decompositions:

5 + 8667871 = 8667876
13 + 8667863 = 8667876
29 + 8667847 = 8667876
47 + 8667829 = 8667876
67 + 8667809 = 8667876
79 + 8667797 = 8667876
83 + 8667793 = 8667876
149 + 8667727 = 8667876

Showing the first eight; more decompositions exist.
