Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601678, here are decompositions:

11 + 8601667 = 8601678
31 + 8601647 = 8601678
37 + 8601641 = 8601678
47 + 8601631 = 8601678
97 + 8601581 = 8601678
109 + 8601569 = 8601678
167 + 8601511 = 8601678
179 + 8601499 = 8601678

Showing the first eight; more decompositions exist.
