Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628218, here are decompositions:

31 + 8628187 = 8628218
37 + 8628181 = 8628218
61 + 8628157 = 8628218
97 + 8628121 = 8628218
199 + 8628019 = 8628218
211 + 8628007 = 8628218
241 + 8627977 = 8628218
271 + 8627947 = 8628218

Showing the first eight; more decompositions exist.
