Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678768, here are decompositions:

19 + 8678749 = 8678768
61 + 8678707 = 8678768
67 + 8678701 = 8678768
97 + 8678671 = 8678768
181 + 8678587 = 8678768
211 + 8678557 = 8678768
409 + 8678359 = 8678768
457 + 8678311 = 8678768

Showing the first eight; more decompositions exist.
