Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667680, here are decompositions:

3 + 8667677 = 8667680
19 + 8667661 = 8667680
67 + 8667613 = 8667680
79 + 8667601 = 8667680
223 + 8667457 = 8667680
277 + 8667403 = 8667680
331 + 8667349 = 8667680
367 + 8667313 = 8667680

Showing the first eight; more decompositions exist.
