Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66208, here are decompositions:

17 + 66191 = 66208
29 + 66179 = 66208
47 + 66161 = 66208
71 + 66137 = 66208
101 + 66107 = 66208
137 + 66071 = 66208
167 + 66041 = 66208
179 + 66029 = 66208

Showing the first eight; more decompositions exist.
