Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939644, here are decompositions:

31 + 939613 = 939644
157 + 939487 = 939644
193 + 939451 = 939644
271 + 939373 = 939644
283 + 939361 = 939644
397 + 939247 = 939644
463 + 939181 = 939644
487 + 939157 = 939644

Showing the first eight; more decompositions exist.
