Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509982, here are decompositions:

19 + 509963 = 509982
23 + 509959 = 509982
43 + 509939 = 509982
61 + 509921 = 509982
71 + 509911 = 509982
73 + 509909 = 509982
103 + 509879 = 509982
139 + 509843 = 509982

Showing the first eight; more decompositions exist.
