Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649384, here are decompositions:

13 + 8649371 = 8649384
17 + 8649367 = 8649384
31 + 8649353 = 8649384
41 + 8649343 = 8649384
53 + 8649331 = 8649384
61 + 8649323 = 8649384
67 + 8649317 = 8649384
101 + 8649283 = 8649384

Showing the first eight; more decompositions exist.
