Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939668, here are decompositions:

7 + 939661 = 939668
19 + 939649 = 939668
157 + 939511 = 939668
181 + 939487 = 939668
199 + 939469 = 939668
229 + 939439 = 939668
277 + 939391 = 939668
307 + 939361 = 939668

Showing the first eight; more decompositions exist.
