Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939500, here are decompositions:

13 + 939487 = 939500
31 + 939469 = 939500
61 + 939439 = 939500
109 + 939391 = 939500
127 + 939373 = 939500
139 + 939361 = 939500
151 + 939349 = 939500
271 + 939229 = 939500

Showing the first eight; more decompositions exist.
