Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939786, here are decompositions:

13 + 939773 = 939786
17 + 939769 = 939786
19 + 939767 = 939786
37 + 939749 = 939786
47 + 939739 = 939786
73 + 939713 = 939786
79 + 939707 = 939786
109 + 939677 = 939786

Showing the first eight; more decompositions exist.
