Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649074, here are decompositions:

3 + 8649071 = 8649074
13 + 8649061 = 8649074
73 + 8649001 = 8649074
151 + 8648923 = 8649074
193 + 8648881 = 8649074
211 + 8648863 = 8649074
241 + 8648833 = 8649074
277 + 8648797 = 8649074

Showing the first eight; more decompositions exist.
