Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939986, here are decompositions:

13 + 939973 = 939986
139 + 939847 = 939986
163 + 939823 = 939986
193 + 939793 = 939986
337 + 939649 = 939986
373 + 939613 = 939986
499 + 939487 = 939986
547 + 939439 = 939986

Showing the first eight; more decompositions exist.
