Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66118, here are decompositions:

11 + 66107 = 66118
29 + 66089 = 66118
47 + 66071 = 66118
71 + 66047 = 66118
89 + 66029 = 66118
137 + 65981 = 66118
167 + 65951 = 66118
191 + 65927 = 66118

Showing the first eight; more decompositions exist.
