Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649506, here are decompositions:

37 + 8649469 = 8649506
43 + 8649463 = 8649506
97 + 8649409 = 8649506
139 + 8649367 = 8649506
157 + 8649349 = 8649506
163 + 8649343 = 8649506
223 + 8649283 = 8649506
457 + 8649049 = 8649506

Showing the first eight; more decompositions exist.
