Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649650, here are decompositions:

13 + 8649637 = 8649650
181 + 8649469 = 8649650
199 + 8649451 = 8649650
241 + 8649409 = 8649650
283 + 8649367 = 8649650
307 + 8649343 = 8649650
367 + 8649283 = 8649650
397 + 8649253 = 8649650

Showing the first eight; more decompositions exist.
