Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519530, here are decompositions:

3 + 519527 = 519530
7 + 519523 = 519530
31 + 519499 = 519530
43 + 519487 = 519530
73 + 519457 = 519530
97 + 519433 = 519530
103 + 519427 = 519530
139 + 519391 = 519530

Showing the first eight; more decompositions exist.
