Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66016, here are decompositions:

23 + 65993 = 66016
53 + 65963 = 66016
59 + 65957 = 66016
89 + 65927 = 66016
149 + 65867 = 66016
173 + 65843 = 66016
179 + 65837 = 66016
227 + 65789 = 66016

Showing the first eight; more decompositions exist.
