Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649456, here are decompositions:

5 + 8649451 = 8649456
37 + 8649419 = 8649456
47 + 8649409 = 8649456
73 + 8649383 = 8649456
89 + 8649367 = 8649456
103 + 8649353 = 8649456
107 + 8649349 = 8649456
113 + 8649343 = 8649456

Showing the first eight; more decompositions exist.
