Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509810, here are decompositions:

13 + 509797 = 509810
43 + 509767 = 509810
73 + 509737 = 509810
79 + 509731 = 509810
151 + 509659 = 509810
157 + 509653 = 509810
163 + 509647 = 509810
229 + 509581 = 509810

Showing the first eight; more decompositions exist.
