Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649104, here are decompositions:

43 + 8649061 = 8649104
103 + 8649001 = 8649104
151 + 8648953 = 8649104
181 + 8648923 = 8649104
223 + 8648881 = 8649104
241 + 8648863 = 8649104
271 + 8648833 = 8649104
307 + 8648797 = 8649104

Showing the first eight; more decompositions exist.
