Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628198, here are decompositions:

11 + 8628187 = 8628198
17 + 8628181 = 8628198
37 + 8628161 = 8628198
41 + 8628157 = 8628198
67 + 8628131 = 8628198
101 + 8628097 = 8628198
149 + 8628049 = 8628198
167 + 8628031 = 8628198

Showing the first eight; more decompositions exist.
