Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939982, here are decompositions:

11 + 939971 = 939982
59 + 939923 = 939982
101 + 939881 = 939982
191 + 939791 = 939982
233 + 939749 = 939982
269 + 939713 = 939982
359 + 939623 = 939982
383 + 939599 = 939982

Showing the first eight; more decompositions exist.
