Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616678, here are decompositions:

17 + 8616661 = 8616678
79 + 8616599 = 8616678
131 + 8616547 = 8616678
137 + 8616541 = 8616678
151 + 8616527 = 8616678
179 + 8616499 = 8616678
271 + 8616407 = 8616678
281 + 8616397 = 8616678

Showing the first eight; more decompositions exist.
