Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649318, here are decompositions:

19 + 8649299 = 8649318
79 + 8649239 = 8649318
107 + 8649211 = 8649318
127 + 8649191 = 8649318
131 + 8649187 = 8649318
239 + 8649079 = 8649318
257 + 8649061 = 8649318
269 + 8649049 = 8649318

Showing the first eight; more decompositions exist.
