Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65604, here are decompositions:

5 + 65599 = 65604
17 + 65587 = 65604
23 + 65581 = 65604
41 + 65563 = 65604
47 + 65557 = 65604
53 + 65551 = 65604
61 + 65543 = 65604
67 + 65537 = 65604

Showing the first eight; more decompositions exist.
