Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65216, here are decompositions:

3 + 65213 = 65216
13 + 65203 = 65216
37 + 65179 = 65216
43 + 65173 = 65216
97 + 65119 = 65216
127 + 65089 = 65216
163 + 65053 = 65216
337 + 64879 = 65216

Showing the first eight; more decompositions exist.
