Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939958, here are decompositions:

167 + 939791 = 939958
191 + 939767 = 939958
251 + 939707 = 939958
281 + 939677 = 939958
347 + 939611 = 939958
359 + 939599 = 939958
599 + 939359 = 939958
641 + 939317 = 939958

Showing the first eight; more decompositions exist.
