Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667800, here are decompositions:

3 + 8667797 = 8667800
7 + 8667793 = 8667800
67 + 8667733 = 8667800
73 + 8667727 = 8667800
79 + 8667721 = 8667800
103 + 8667697 = 8667800
139 + 8667661 = 8667800
199 + 8667601 = 8667800

Showing the first eight; more decompositions exist.
