Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649252, here are decompositions:

11 + 8649241 = 8649252
13 + 8649239 = 8649252
41 + 8649211 = 8649252
61 + 8649191 = 8649252
149 + 8649103 = 8649252
173 + 8649079 = 8649252
181 + 8649071 = 8649252
191 + 8649061 = 8649252

Showing the first eight; more decompositions exist.
