Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678918, here are decompositions:

19 + 8678899 = 8678918
67 + 8678851 = 8678918
97 + 8678821 = 8678918
139 + 8678779 = 8678918
211 + 8678707 = 8678918
331 + 8678587 = 8678918
337 + 8678581 = 8678918
607 + 8678311 = 8678918

Showing the first eight; more decompositions exist.
