Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647170, here are decompositions:

13 + 8647157 = 8647170
31 + 8647139 = 8647170
41 + 8647129 = 8647170
43 + 8647127 = 8647170
47 + 8647123 = 8647170
79 + 8647091 = 8647170
107 + 8647063 = 8647170
109 + 8647061 = 8647170

Showing the first eight; more decompositions exist.
