Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519528, here are decompositions:

5 + 519523 = 519528
7 + 519521 = 519528
19 + 519509 = 519528
29 + 519499 = 519528
41 + 519487 = 519528
71 + 519457 = 519528
101 + 519427 = 519528
137 + 519391 = 519528

Showing the first eight; more decompositions exist.
