Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509880, here are decompositions:

13 + 509867 = 509880
17 + 509863 = 509880
37 + 509843 = 509880
43 + 509837 = 509880
47 + 509833 = 509880
79 + 509801 = 509880
83 + 509797 = 509880
97 + 509783 = 509880

Showing the first eight; more decompositions exist.
