Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519756, here are decompositions:

19 + 519737 = 519756
23 + 519733 = 519756
43 + 519713 = 519756
53 + 519703 = 519756
73 + 519683 = 519756
89 + 519667 = 519756
109 + 519647 = 519756
113 + 519643 = 519756

Showing the first eight; more decompositions exist.
