Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939388, here are decompositions:

11 + 939377 = 939388
29 + 939359 = 939388
41 + 939347 = 939388
71 + 939317 = 939388
89 + 939299 = 939388
101 + 939287 = 939388
269 + 939119 = 939388
419 + 938969 = 939388

Showing the first eight; more decompositions exist.
