Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519902, here are decompositions:

13 + 519889 = 519902
109 + 519793 = 519902
199 + 519703 = 519902
211 + 519691 = 519902
283 + 519619 = 519902
349 + 519553 = 519902
379 + 519523 = 519902
601 + 519301 = 519902

Showing the first eight; more decompositions exist.
