Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939836, here are decompositions:

13 + 939823 = 939836
43 + 939793 = 939836
67 + 939769 = 939836
97 + 939739 = 939836
223 + 939613 = 939836
349 + 939487 = 939836
367 + 939469 = 939836
397 + 939439 = 939836

Showing the first eight; more decompositions exist.
