Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939972, here are decompositions:

41 + 939931 = 939972
71 + 939901 = 939972
101 + 939871 = 939972
149 + 939823 = 939972
179 + 939793 = 939972
181 + 939791 = 939972
199 + 939773 = 939972
223 + 939749 = 939972

Showing the first eight; more decompositions exist.
