Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678566, here are decompositions:

47 + 8678519 = 8678566
59 + 8678507 = 8678566
167 + 8678399 = 8678566
173 + 8678393 = 8678566
227 + 8678339 = 8678566
233 + 8678333 = 8678566
353 + 8678213 = 8678566
419 + 8678147 = 8678566

Showing the first eight; more decompositions exist.
