Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509946, here are decompositions:

7 + 509939 = 509946
37 + 509909 = 509946
67 + 509879 = 509946
79 + 509867 = 509946
83 + 509863 = 509946
103 + 509843 = 509946
109 + 509837 = 509946
113 + 509833 = 509946

Showing the first eight; more decompositions exist.
