Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670216, here are decompositions:

19 + 8670197 = 8670216
59 + 8670157 = 8670216
89 + 8670127 = 8670216
109 + 8670107 = 8670216
127 + 8670089 = 8670216
179 + 8670037 = 8670216
223 + 8669993 = 8670216
227 + 8669989 = 8670216

Showing the first eight; more decompositions exist.
