Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678686, here are decompositions:

17 + 8678669 = 8678686
47 + 8678639 = 8678686
83 + 8678603 = 8678686
167 + 8678519 = 8678686
179 + 8678507 = 8678686
239 + 8678447 = 8678686
293 + 8678393 = 8678686
347 + 8678339 = 8678686

Showing the first eight; more decompositions exist.
