Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939470, here are decompositions:

19 + 939451 = 939470
31 + 939439 = 939470
79 + 939391 = 939470
97 + 939373 = 939470
109 + 939361 = 939470
223 + 939247 = 939470
241 + 939229 = 939470
277 + 939193 = 939470

Showing the first eight; more decompositions exist.
