Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65320, here are decompositions:

11 + 65309 = 65320
53 + 65267 = 65320
107 + 65213 = 65320
137 + 65183 = 65320
149 + 65171 = 65320
173 + 65147 = 65320
179 + 65141 = 65320
191 + 65129 = 65320

Showing the first eight; more decompositions exist.
