Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939806, here are decompositions:

13 + 939793 = 939806
37 + 939769 = 939806
67 + 939739 = 939806
157 + 939649 = 939806
193 + 939613 = 939806
337 + 939469 = 939806
367 + 939439 = 939806
433 + 939373 = 939806

Showing the first eight; more decompositions exist.
