Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678390, here are decompositions:

31 + 8678359 = 8678390
37 + 8678353 = 8678390
67 + 8678323 = 8678390
79 + 8678311 = 8678390
211 + 8678179 = 8678390
229 + 8678161 = 8678390
241 + 8678149 = 8678390
277 + 8678113 = 8678390

Showing the first eight; more decompositions exist.
