Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939850, here are decompositions:

3 + 939847 = 939850
11 + 939839 = 939850
59 + 939791 = 939850
83 + 939767 = 939850
101 + 939749 = 939850
113 + 939737 = 939850
137 + 939713 = 939850
173 + 939677 = 939850

Showing the first eight; more decompositions exist.
