Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939866, here are decompositions:

13 + 939853 = 939866
19 + 939847 = 939866
43 + 939823 = 939866
73 + 939793 = 939866
97 + 939769 = 939866
127 + 939739 = 939866
379 + 939487 = 939866
397 + 939469 = 939866

Showing the first eight; more decompositions exist.
