Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939870, here are decompositions:

17 + 939853 = 939870
23 + 939847 = 939870
31 + 939839 = 939870
47 + 939823 = 939870
79 + 939791 = 939870
97 + 939773 = 939870
101 + 939769 = 939870
103 + 939767 = 939870

Showing the first eight; more decompositions exist.
