Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509968, here are decompositions:

5 + 509963 = 509968
29 + 509939 = 509968
47 + 509921 = 509968
59 + 509909 = 509968
89 + 509879 = 509968
101 + 509867 = 509968
131 + 509837 = 509968
167 + 509801 = 509968

Showing the first eight; more decompositions exist.
