Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728678, here are decompositions:

29 + 8728649 = 8728678
71 + 8728607 = 8728678
107 + 8728571 = 8728678
197 + 8728481 = 8728678
251 + 8728427 = 8728678
281 + 8728397 = 8728678
347 + 8728331 = 8728678
389 + 8728289 = 8728678

Showing the first eight; more decompositions exist.
