Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 930840, here are decompositions:

13 + 930827 = 930840
23 + 930817 = 930840
61 + 930779 = 930840
67 + 930773 = 930840
103 + 930737 = 930840
151 + 930689 = 930840
173 + 930667 = 930840
223 + 930617 = 930840

Showing the first eight; more decompositions exist.
