Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519922, here are decompositions:

3 + 519919 = 519922
5 + 519917 = 519922
41 + 519881 = 519922
59 + 519863 = 519922
239 + 519683 = 519922
311 + 519611 = 519922
383 + 519539 = 519922
401 + 519521 = 519922

Showing the first eight; more decompositions exist.
