Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939404, here are decompositions:

13 + 939391 = 939404
31 + 939373 = 939404
43 + 939361 = 939404
157 + 939247 = 939404
211 + 939193 = 939404
223 + 939181 = 939404
283 + 939121 = 939404
313 + 939091 = 939404

Showing the first eight; more decompositions exist.
