Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667380, here are decompositions:

3 + 8667377 = 8667380
31 + 8667349 = 8667380
61 + 8667319 = 8667380
67 + 8667313 = 8667380
79 + 8667301 = 8667380
109 + 8667271 = 8667380
229 + 8667151 = 8667380
277 + 8667103 = 8667380

Showing the first eight; more decompositions exist.
