Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656684, here are decompositions:

17 + 8656667 = 8656684
107 + 8656577 = 8656684
137 + 8656547 = 8656684
167 + 8656517 = 8656684
173 + 8656511 = 8656684
191 + 8656493 = 8656684
251 + 8656433 = 8656684
317 + 8656367 = 8656684

Showing the first eight; more decompositions exist.
