Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939908, here are decompositions:

7 + 939901 = 939908
37 + 939871 = 939908
61 + 939847 = 939908
139 + 939769 = 939908
397 + 939511 = 939908
421 + 939487 = 939908
439 + 939469 = 939908
457 + 939451 = 939908

Showing the first eight; more decompositions exist.
