Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678628, here are decompositions:

29 + 8678599 = 8678628
41 + 8678587 = 8678628
47 + 8678581 = 8678628
71 + 8678557 = 8678628
109 + 8678519 = 8678628
181 + 8678447 = 8678628
229 + 8678399 = 8678628
269 + 8678359 = 8678628

Showing the first eight; more decompositions exist.
