Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993858, here are decompositions:

7 + 993851 = 993858
17 + 993841 = 993858
31 + 993827 = 993858
37 + 993821 = 993858
79 + 993779 = 993858
179 + 993679 = 993858
211 + 993647 = 993858
241 + 993617 = 993858

Showing the first eight; more decompositions exist.
