Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519780, here are decompositions:

11 + 519769 = 519780
43 + 519737 = 519780
47 + 519733 = 519780
67 + 519713 = 519780
89 + 519691 = 519780
97 + 519683 = 519780
113 + 519667 = 519780
137 + 519643 = 519780

Showing the first eight; more decompositions exist.
