Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519906, here are decompositions:

17 + 519889 = 519906
43 + 519863 = 519906
89 + 519817 = 519906
103 + 519803 = 519906
109 + 519797 = 519906
113 + 519793 = 519906
137 + 519769 = 519906
173 + 519733 = 519906

Showing the first eight; more decompositions exist.
