Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519390, here are decompositions:

7 + 519383 = 519390
17 + 519373 = 519390
19 + 519371 = 519390
31 + 519359 = 519390
37 + 519353 = 519390
41 + 519349 = 519390
83 + 519307 = 519390
89 + 519301 = 519390

Showing the first eight; more decompositions exist.
