Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66342, here are decompositions:

5 + 66337 = 66342
41 + 66301 = 66342
71 + 66271 = 66342
103 + 66239 = 66342
151 + 66191 = 66342
163 + 66179 = 66342
173 + 66169 = 66342
181 + 66161 = 66342

Showing the first eight; more decompositions exist.
