Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519442, here are decompositions:

29 + 519413 = 519442
59 + 519383 = 519442
71 + 519371 = 519442
83 + 519359 = 519442
89 + 519353 = 519442
173 + 519269 = 519442
281 + 519161 = 519442
311 + 519131 = 519442

Showing the first eight; more decompositions exist.
