Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667440, here are decompositions:

13 + 8667427 = 8667440
37 + 8667403 = 8667440
127 + 8667313 = 8667440
139 + 8667301 = 8667440
151 + 8667289 = 8667440
337 + 8667103 = 8667440
487 + 8666953 = 8667440
577 + 8666863 = 8667440

Showing the first eight; more decompositions exist.
