Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509950, here are decompositions:

3 + 509947 = 509950
11 + 509939 = 509950
29 + 509921 = 509950
41 + 509909 = 509950
71 + 509879 = 509950
83 + 509867 = 509950
107 + 509843 = 509950
113 + 509837 = 509950

Showing the first eight; more decompositions exist.
