Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667640, here are decompositions:

29 + 8667611 = 8667640
101 + 8667539 = 8667640
227 + 8667413 = 8667640
263 + 8667377 = 8667640
269 + 8667371 = 8667640
383 + 8667257 = 8667640
461 + 8667179 = 8667640
503 + 8667137 = 8667640

Showing the first eight; more decompositions exist.
