Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519402, here are decompositions:

11 + 519391 = 519402
19 + 519383 = 519402
29 + 519373 = 519402
31 + 519371 = 519402
43 + 519359 = 519402
53 + 519349 = 519402
101 + 519301 = 519402
173 + 519229 = 519402

Showing the first eight; more decompositions exist.
