Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66340, here are decompositions:

3 + 66337 = 66340
47 + 66293 = 66340
101 + 66239 = 66340
149 + 66191 = 66340
167 + 66173 = 66340
179 + 66161 = 66340
233 + 66107 = 66340
251 + 66089 = 66340

Showing the first eight; more decompositions exist.
