Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66148, here are decompositions:

11 + 66137 = 66148
41 + 66107 = 66148
59 + 66089 = 66148
101 + 66047 = 66148
107 + 66041 = 66148
167 + 65981 = 66148
191 + 65957 = 66148
197 + 65951 = 66148

Showing the first eight; more decompositions exist.
