Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65402, here are decompositions:

31 + 65371 = 65402
79 + 65323 = 65402
109 + 65293 = 65402
163 + 65239 = 65402
199 + 65203 = 65402
223 + 65179 = 65402
229 + 65173 = 65402
283 + 65119 = 65402

Showing the first eight; more decompositions exist.
