Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986942, here are decompositions:

13 + 986929 = 986942
163 + 986779 = 986942
193 + 986749 = 986942
223 + 986719 = 986942
283 + 986659 = 986942
349 + 986593 = 986942
373 + 986569 = 986942
379 + 986563 = 986942

Showing the first eight; more decompositions exist.
