Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649164, here are decompositions:

61 + 8649103 = 8649164
103 + 8649061 = 8649164
163 + 8649001 = 8649164
211 + 8648953 = 8649164
241 + 8648923 = 8649164
283 + 8648881 = 8649164
331 + 8648833 = 8649164
367 + 8648797 = 8649164

Showing the first eight; more decompositions exist.
