Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509814, here are decompositions:

13 + 509801 = 509814
17 + 509797 = 509814
31 + 509783 = 509814
47 + 509767 = 509814
73 + 509741 = 509814
83 + 509731 = 509814
127 + 509687 = 509814
167 + 509647 = 509814

Showing the first eight; more decompositions exist.
