Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646, here are decompositions:

5 + 8641 = 8646
17 + 8629 = 8646
19 + 8627 = 8646
23 + 8623 = 8646
37 + 8609 = 8646
47 + 8599 = 8646
73 + 8573 = 8646
83 + 8563 = 8646

Showing the first eight; more decompositions exist.
