Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519900, here are decompositions:

11 + 519889 = 519900
19 + 519881 = 519900
37 + 519863 = 519900
83 + 519817 = 519900
97 + 519803 = 519900
103 + 519797 = 519900
107 + 519793 = 519900
113 + 519787 = 519900

Showing the first eight; more decompositions exist.
