Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649740, here are decompositions:

19 + 8649721 = 8649740
37 + 8649703 = 8649740
79 + 8649661 = 8649740
103 + 8649637 = 8649740
223 + 8649517 = 8649740
271 + 8649469 = 8649740
277 + 8649463 = 8649740
331 + 8649409 = 8649740

Showing the first eight; more decompositions exist.
