Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509980, here are decompositions:

17 + 509963 = 509980
41 + 509939 = 509980
59 + 509921 = 509980
71 + 509909 = 509980
101 + 509879 = 509980
113 + 509867 = 509980
137 + 509843 = 509980
179 + 509801 = 509980

Showing the first eight; more decompositions exist.
