Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939824, here are decompositions:

31 + 939793 = 939824
163 + 939661 = 939824
211 + 939613 = 939824
313 + 939511 = 939824
337 + 939487 = 939824
373 + 939451 = 939824
433 + 939391 = 939824
463 + 939361 = 939824

Showing the first eight; more decompositions exist.
