Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939818, here are decompositions:

79 + 939739 = 939818
157 + 939661 = 939818
307 + 939511 = 939818
331 + 939487 = 939818
349 + 939469 = 939818
367 + 939451 = 939818
379 + 939439 = 939818
457 + 939361 = 939818

Showing the first eight; more decompositions exist.
