Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709170, here are decompositions:

31 + 8709139 = 8709170
37 + 8709133 = 8709170
103 + 8709067 = 8709170
163 + 8709007 = 8709170
199 + 8708971 = 8709170
277 + 8708893 = 8709170
367 + 8708803 = 8709170
439 + 8708731 = 8709170

Showing the first eight; more decompositions exist.
