Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65506, here are decompositions:

59 + 65447 = 65506
83 + 65423 = 65506
113 + 65393 = 65506
149 + 65357 = 65506
179 + 65327 = 65506
197 + 65309 = 65506
239 + 65267 = 65506
293 + 65213 = 65506

Showing the first eight; more decompositions exist.
