Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683664, here are decompositions:

7 + 8683657 = 8683664
61 + 8683603 = 8683664
181 + 8683483 = 8683664
211 + 8683453 = 8683664
271 + 8683393 = 8683664
337 + 8683327 = 8683664
433 + 8683231 = 8683664
463 + 8683201 = 8683664

Showing the first eight; more decompositions exist.
