Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519540, here are decompositions:

13 + 519527 = 519540
17 + 519523 = 519540
19 + 519521 = 519540
31 + 519509 = 519540
41 + 519499 = 519540
53 + 519487 = 519540
83 + 519457 = 519540
107 + 519433 = 519540

Showing the first eight; more decompositions exist.
