Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649450, here are decompositions:

31 + 8649419 = 8649450
41 + 8649409 = 8649450
59 + 8649391 = 8649450
67 + 8649383 = 8649450
79 + 8649371 = 8649450
83 + 8649367 = 8649450
97 + 8649353 = 8649450
101 + 8649349 = 8649450

Showing the first eight; more decompositions exist.
