Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939406, here are decompositions:

29 + 939377 = 939406
47 + 939359 = 939406
59 + 939347 = 939406
89 + 939317 = 939406
107 + 939299 = 939406
113 + 939293 = 939406
227 + 939179 = 939406
239 + 939167 = 939406

Showing the first eight; more decompositions exist.
