Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509976, here are decompositions:

13 + 509963 = 509976
17 + 509959 = 509976
29 + 509947 = 509976
37 + 509939 = 509976
67 + 509909 = 509976
97 + 509879 = 509976
109 + 509867 = 509976
113 + 509863 = 509976

Showing the first eight; more decompositions exist.
