Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939910, here are decompositions:

29 + 939881 = 939910
71 + 939839 = 939910
137 + 939773 = 939910
173 + 939737 = 939910
197 + 939713 = 939910
233 + 939677 = 939910
311 + 939599 = 939910
359 + 939551 = 939910

Showing the first eight; more decompositions exist.
