Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646670, here are decompositions:

3 + 8646667 = 8646670
89 + 8646581 = 8646670
167 + 8646503 = 8646670
173 + 8646497 = 8646670
191 + 8646479 = 8646670
269 + 8646401 = 8646670
281 + 8646389 = 8646670
293 + 8646377 = 8646670

Showing the first eight; more decompositions exist.
