Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939518, here are decompositions:

7 + 939511 = 939518
31 + 939487 = 939518
67 + 939451 = 939518
79 + 939439 = 939518
127 + 939391 = 939518
157 + 939361 = 939518
271 + 939247 = 939518
337 + 939181 = 939518

Showing the first eight; more decompositions exist.
