Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509846, here are decompositions:

3 + 509843 = 509846
13 + 509833 = 509846
79 + 509767 = 509846
109 + 509737 = 509846
157 + 509689 = 509846
193 + 509653 = 509846
199 + 509647 = 509846
223 + 509623 = 509846

Showing the first eight; more decompositions exist.
