Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668678, here are decompositions:

41 + 8668637 = 8668678
101 + 8668577 = 8668678
107 + 8668571 = 8668678
131 + 8668547 = 8668678
257 + 8668421 = 8668678
311 + 8668367 = 8668678
521 + 8668157 = 8668678
617 + 8668061 = 8668678

Showing the first eight; more decompositions exist.
