Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678464, here are decompositions:

17 + 8678447 = 8678464
71 + 8678393 = 8678464
101 + 8678363 = 8678464
131 + 8678333 = 8678464
227 + 8678237 = 8678464
251 + 8678213 = 8678464
317 + 8678147 = 8678464
383 + 8678081 = 8678464

Showing the first eight; more decompositions exist.
