Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678930, here are decompositions:

3 + 8678927 = 8678930
31 + 8678899 = 8678930
37 + 8678893 = 8678930
67 + 8678863 = 8678930
79 + 8678851 = 8678930
97 + 8678833 = 8678930
109 + 8678821 = 8678930
151 + 8678779 = 8678930

Showing the first eight; more decompositions exist.
