Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519880, here are decompositions:

17 + 519863 = 519880
83 + 519797 = 519880
167 + 519713 = 519880
197 + 519683 = 519880
233 + 519647 = 519880
269 + 519611 = 519880
293 + 519587 = 519880
353 + 519527 = 519880

Showing the first eight; more decompositions exist.
