Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519826, here are decompositions:

23 + 519803 = 519826
29 + 519797 = 519826
89 + 519737 = 519826
113 + 519713 = 519826
179 + 519647 = 519826
239 + 519587 = 519826
317 + 519509 = 519826
443 + 519383 = 519826

Showing the first eight; more decompositions exist.
