Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939998, here are decompositions:

67 + 939931 = 939998
97 + 939901 = 939998
127 + 939871 = 939998
151 + 939847 = 939998
229 + 939769 = 939998
337 + 939661 = 939998
349 + 939649 = 939998
487 + 939511 = 939998

Showing the first eight; more decompositions exist.
