Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678560, here are decompositions:

3 + 8678557 = 8678560
41 + 8678519 = 8678560
53 + 8678507 = 8678560
113 + 8678447 = 8678560
167 + 8678393 = 8678560
197 + 8678363 = 8678560
227 + 8678333 = 8678560
347 + 8678213 = 8678560

Showing the first eight; more decompositions exist.
