Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66178, here are decompositions:

5 + 66173 = 66178
17 + 66161 = 66178
41 + 66137 = 66178
71 + 66107 = 66178
89 + 66089 = 66178
107 + 66071 = 66178
131 + 66047 = 66178
137 + 66041 = 66178

Showing the first eight; more decompositions exist.
