Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509894, here are decompositions:

31 + 509863 = 509894
61 + 509833 = 509894
97 + 509797 = 509894
127 + 509767 = 509894
157 + 509737 = 509894
163 + 509731 = 509894
241 + 509653 = 509894
271 + 509623 = 509894

Showing the first eight; more decompositions exist.
