Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65256, here are decompositions:

17 + 65239 = 65256
43 + 65213 = 65256
53 + 65203 = 65256
73 + 65183 = 65256
83 + 65173 = 65256
89 + 65167 = 65256
109 + 65147 = 65256
127 + 65129 = 65256

Showing the first eight; more decompositions exist.
