Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939380, here are decompositions:

3 + 939377 = 939380
7 + 939373 = 939380
19 + 939361 = 939380
31 + 939349 = 939380
151 + 939229 = 939380
199 + 939181 = 939380
223 + 939157 = 939380
271 + 939109 = 939380

Showing the first eight; more decompositions exist.
