Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649228, here are decompositions:

17 + 8649211 = 8649228
31 + 8649197 = 8649228
37 + 8649191 = 8649228
41 + 8649187 = 8649228
149 + 8649079 = 8649228
157 + 8649071 = 8649228
167 + 8649061 = 8649228
179 + 8649049 = 8649228

Showing the first eight; more decompositions exist.
