Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66160, here are decompositions:

23 + 66137 = 66160
53 + 66107 = 66160
71 + 66089 = 66160
89 + 66071 = 66160
113 + 66047 = 66160
131 + 66029 = 66160
167 + 65993 = 66160
179 + 65981 = 66160

Showing the first eight; more decompositions exist.
