Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656678, here are decompositions:

11 + 8656667 = 8656678
89 + 8656589 = 8656678
101 + 8656577 = 8656678
131 + 8656547 = 8656678
167 + 8656511 = 8656678
179 + 8656499 = 8656678
197 + 8656481 = 8656678
311 + 8656367 = 8656678

Showing the first eight; more decompositions exist.
