Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65660, here are decompositions:

3 + 65657 = 65660
13 + 65647 = 65660
31 + 65629 = 65660
43 + 65617 = 65660
61 + 65599 = 65660
73 + 65587 = 65660
79 + 65581 = 65660
97 + 65563 = 65660

Showing the first eight; more decompositions exist.
