Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667140, here are decompositions:

3 + 8667137 = 8667140
19 + 8667121 = 8667140
37 + 8667103 = 8667140
61 + 8667079 = 8667140
151 + 8666989 = 8667140
277 + 8666863 = 8667140
331 + 8666809 = 8667140
367 + 8666773 = 8667140

Showing the first eight; more decompositions exist.
