Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65286, here are decompositions:

17 + 65269 = 65286
19 + 65267 = 65286
29 + 65257 = 65286
47 + 65239 = 65286
73 + 65213 = 65286
83 + 65203 = 65286
103 + 65183 = 65286
107 + 65179 = 65286

Showing the first eight; more decompositions exist.
