Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678798, here are decompositions:

19 + 8678779 = 8678798
97 + 8678701 = 8678798
127 + 8678671 = 8678798
199 + 8678599 = 8678798
211 + 8678587 = 8678798
241 + 8678557 = 8678798
439 + 8678359 = 8678798
487 + 8678311 = 8678798

Showing the first eight; more decompositions exist.
