Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678198, here are decompositions:

19 + 8678179 = 8678198
37 + 8678161 = 8678198
307 + 8677891 = 8678198
439 + 8677759 = 8678198
547 + 8677651 = 8678198
811 + 8677387 = 8678198
937 + 8677261 = 8678198
1171 + 8677027 = 8678198

Showing the first eight; more decompositions exist.
