Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65540, here are decompositions:

3 + 65537 = 65540
19 + 65521 = 65540
43 + 65497 = 65540
61 + 65479 = 65540
103 + 65437 = 65540
127 + 65413 = 65540
271 + 65269 = 65540
283 + 65257 = 65540

Showing the first eight; more decompositions exist.
