Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65530, here are decompositions:

11 + 65519 = 65530
83 + 65447 = 65530
107 + 65423 = 65530
137 + 65393 = 65530
149 + 65381 = 65530
173 + 65357 = 65530
263 + 65267 = 65530
317 + 65213 = 65530

Showing the first eight; more decompositions exist.
