Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943818, here are decompositions:

17 + 943801 = 943818
19 + 943799 = 943818
37 + 943781 = 943818
41 + 943777 = 943818
61 + 943757 = 943818
67 + 943751 = 943818
89 + 943729 = 943818
167 + 943651 = 943818

Showing the first eight; more decompositions exist.
