Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166322, here are decompositions:

3 + 166319 = 166322
19 + 166303 = 166322
103 + 166219 = 166322
139 + 166183 = 166322
223 + 166099 = 166322
241 + 166081 = 166322
421 + 165901 = 166322
439 + 165883 = 166322

Showing the first eight; more decompositions exist.
