Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943786, here are decompositions:

3 + 943783 = 943786
5 + 943781 = 943786
17 + 943769 = 943786
23 + 943763 = 943786
29 + 943757 = 943786
149 + 943637 = 943786
197 + 943589 = 943786
383 + 943403 = 943786

Showing the first eight; more decompositions exist.
