Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649426, here are decompositions:

7 + 8649419 = 8649426
17 + 8649409 = 8649426
43 + 8649383 = 8649426
59 + 8649367 = 8649426
73 + 8649353 = 8649426
83 + 8649343 = 8649426
103 + 8649323 = 8649426
109 + 8649317 = 8649426

Showing the first eight; more decompositions exist.
