Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939770, here are decompositions:

3 + 939767 = 939770
31 + 939739 = 939770
109 + 939661 = 939770
157 + 939613 = 939770
283 + 939487 = 939770
331 + 939439 = 939770
379 + 939391 = 939770
397 + 939373 = 939770

Showing the first eight; more decompositions exist.
