Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670188, here are decompositions:

31 + 8670157 = 8670188
61 + 8670127 = 8670188
151 + 8670037 = 8670188
157 + 8670031 = 8670188
181 + 8670007 = 8670188
199 + 8669989 = 8670188
277 + 8669911 = 8670188
367 + 8669821 = 8670188

Showing the first eight; more decompositions exist.
