Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509898, here are decompositions:

19 + 509879 = 509898
31 + 509867 = 509898
61 + 509837 = 509898
97 + 509801 = 509898
101 + 509797 = 509898
131 + 509767 = 509898
157 + 509741 = 509898
167 + 509731 = 509898

Showing the first eight; more decompositions exist.
