Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641650, here are decompositions:

7 + 8641643 = 8641650
19 + 8641631 = 8641650
29 + 8641621 = 8641650
37 + 8641613 = 8641650
47 + 8641603 = 8641650
79 + 8641571 = 8641650
103 + 8641547 = 8641650
107 + 8641543 = 8641650

Showing the first eight; more decompositions exist.
