Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939942, here are decompositions:

11 + 939931 = 939942
19 + 939923 = 939942
41 + 939901 = 939942
61 + 939881 = 939942
71 + 939871 = 939942
89 + 939853 = 939942
103 + 939839 = 939942
149 + 939793 = 939942

Showing the first eight; more decompositions exist.
