Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939660, here are decompositions:

11 + 939649 = 939660
37 + 939623 = 939660
47 + 939613 = 939660
61 + 939599 = 939660
79 + 939581 = 939660
109 + 939551 = 939660
149 + 939511 = 939660
173 + 939487 = 939660

Showing the first eight; more decompositions exist.
