Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939542, here are decompositions:

31 + 939511 = 939542
73 + 939469 = 939542
103 + 939439 = 939542
151 + 939391 = 939542
181 + 939361 = 939542
193 + 939349 = 939542
313 + 939229 = 939542
349 + 939193 = 939542

Showing the first eight; more decompositions exist.
