Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65200, here are decompositions:

17 + 65183 = 65200
29 + 65171 = 65200
53 + 65147 = 65200
59 + 65141 = 65200
71 + 65129 = 65200
89 + 65111 = 65200
101 + 65099 = 65200
137 + 65063 = 65200

Showing the first eight; more decompositions exist.
