Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678688, here are decompositions:

17 + 8678671 = 8678688
19 + 8678669 = 8678688
89 + 8678599 = 8678688
101 + 8678587 = 8678688
107 + 8678581 = 8678688
131 + 8678557 = 8678688
181 + 8678507 = 8678688
241 + 8678447 = 8678688

Showing the first eight; more decompositions exist.
