Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519744, here are decompositions:

7 + 519737 = 519744
11 + 519733 = 519744
31 + 519713 = 519744
41 + 519703 = 519744
53 + 519691 = 519744
61 + 519683 = 519744
97 + 519647 = 519744
101 + 519643 = 519744

Showing the first eight; more decompositions exist.
