Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649198, here are decompositions:

7 + 8649191 = 8649198
11 + 8649187 = 8649198
127 + 8649071 = 8649198
137 + 8649061 = 8649198
149 + 8649049 = 8649198
197 + 8649001 = 8649198
269 + 8648929 = 8649198
277 + 8648921 = 8649198

Showing the first eight; more decompositions exist.
