Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605678, here are decompositions:

41 + 8605637 = 8605678
71 + 8605607 = 8605678
101 + 8605577 = 8605678
149 + 8605529 = 8605678
167 + 8605511 = 8605678
197 + 8605481 = 8605678
317 + 8605361 = 8605678
359 + 8605319 = 8605678

Showing the first eight; more decompositions exist.
