Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678678, here are decompositions:

7 + 8678671 = 8678678
79 + 8678599 = 8678678
97 + 8678581 = 8678678
367 + 8678311 = 8678678
499 + 8678179 = 8678678
727 + 8677951 = 8678678
787 + 8677891 = 8678678
907 + 8677771 = 8678678

Showing the first eight; more decompositions exist.
