Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65516, here are decompositions:

19 + 65497 = 65516
37 + 65479 = 65516
67 + 65449 = 65516
79 + 65437 = 65516
97 + 65419 = 65516
103 + 65413 = 65516
109 + 65407 = 65516
163 + 65353 = 65516

Showing the first eight; more decompositions exist.
