Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939402, here are decompositions:

11 + 939391 = 939402
29 + 939373 = 939402
41 + 939361 = 939402
43 + 939359 = 939402
53 + 939349 = 939402
103 + 939299 = 939402
109 + 939293 = 939402
173 + 939229 = 939402

Showing the first eight; more decompositions exist.
