Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939810, here are decompositions:

17 + 939793 = 939810
19 + 939791 = 939810
37 + 939773 = 939810
41 + 939769 = 939810
43 + 939767 = 939810
61 + 939749 = 939810
71 + 939739 = 939810
73 + 939737 = 939810

Showing the first eight; more decompositions exist.
