Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649674, here are decompositions:

3 + 8649671 = 8649674
13 + 8649661 = 8649674
37 + 8649637 = 8649674
157 + 8649517 = 8649674
211 + 8649463 = 8649674
223 + 8649451 = 8649674
283 + 8649391 = 8649674
307 + 8649367 = 8649674

Showing the first eight; more decompositions exist.
