Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939666, here are decompositions:

5 + 939661 = 939666
17 + 939649 = 939666
43 + 939623 = 939666
53 + 939613 = 939666
67 + 939599 = 939666
179 + 939487 = 939666
197 + 939469 = 939666
223 + 939443 = 939666

Showing the first eight; more decompositions exist.
