Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649146, here are decompositions:

43 + 8649103 = 8649146
67 + 8649079 = 8649146
97 + 8649049 = 8649146
193 + 8648953 = 8649146
223 + 8648923 = 8649146
283 + 8648863 = 8649146
307 + 8648839 = 8649146
313 + 8648833 = 8649146

Showing the first eight; more decompositions exist.
