Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65864, here are decompositions:

13 + 65851 = 65864
37 + 65827 = 65864
103 + 65761 = 65864
151 + 65713 = 65864
157 + 65707 = 65864
163 + 65701 = 65864
277 + 65587 = 65864
283 + 65581 = 65864

Showing the first eight; more decompositions exist.
