Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939812, here are decompositions:

19 + 939793 = 939812
43 + 939769 = 939812
73 + 939739 = 939812
151 + 939661 = 939812
163 + 939649 = 939812
199 + 939613 = 939812
373 + 939439 = 939812
421 + 939391 = 939812

Showing the first eight; more decompositions exist.
