Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939882, here are decompositions:

11 + 939871 = 939882
29 + 939853 = 939882
43 + 939839 = 939882
59 + 939823 = 939882
89 + 939793 = 939882
109 + 939773 = 939882
113 + 939769 = 939882
233 + 939649 = 939882

Showing the first eight; more decompositions exist.
