Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939938, here are decompositions:

7 + 939931 = 939938
37 + 939901 = 939938
67 + 939871 = 939938
199 + 939739 = 939938
277 + 939661 = 939938
487 + 939451 = 939938
499 + 939439 = 939938
547 + 939391 = 939938

Showing the first eight; more decompositions exist.
