Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667456, here are decompositions:

29 + 8667427 = 8667456
37 + 8667419 = 8667456
43 + 8667413 = 8667456
53 + 8667403 = 8667456
79 + 8667377 = 8667456
107 + 8667349 = 8667456
137 + 8667319 = 8667456
157 + 8667299 = 8667456

Showing the first eight; more decompositions exist.
