Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939860, here are decompositions:

7 + 939853 = 939860
13 + 939847 = 939860
37 + 939823 = 939860
67 + 939793 = 939860
199 + 939661 = 939860
211 + 939649 = 939860
349 + 939511 = 939860
373 + 939487 = 939860

Showing the first eight; more decompositions exist.
