Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519558, here are decompositions:

5 + 519553 = 519558
7 + 519551 = 519558
19 + 519539 = 519558
31 + 519527 = 519558
37 + 519521 = 519558
59 + 519499 = 519558
71 + 519487 = 519558
101 + 519457 = 519558

Showing the first eight; more decompositions exist.
