Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65866, here are decompositions:

23 + 65843 = 65866
29 + 65837 = 65866
89 + 65777 = 65866
137 + 65729 = 65866
149 + 65717 = 65866
167 + 65699 = 65866
179 + 65687 = 65866
233 + 65633 = 65866

Showing the first eight; more decompositions exist.
