Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65646, here are decompositions:

13 + 65633 = 65646
17 + 65629 = 65646
29 + 65617 = 65646
37 + 65609 = 65646
47 + 65599 = 65646
59 + 65587 = 65646
67 + 65579 = 65646
83 + 65563 = 65646

Showing the first eight; more decompositions exist.
