Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939966, here are decompositions:

43 + 939923 = 939966
113 + 939853 = 939966
127 + 939839 = 939966
173 + 939793 = 939966
193 + 939773 = 939966
197 + 939769 = 939966
199 + 939767 = 939966
227 + 939739 = 939966

Showing the first eight; more decompositions exist.
