Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65810, here are decompositions:

79 + 65731 = 65810
97 + 65713 = 65810
103 + 65707 = 65810
109 + 65701 = 65810
163 + 65647 = 65810
181 + 65629 = 65810
193 + 65617 = 65810
211 + 65599 = 65810

Showing the first eight; more decompositions exist.
