Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519782, here are decompositions:

13 + 519769 = 519782
79 + 519703 = 519782
139 + 519643 = 519782
163 + 519619 = 519782
229 + 519553 = 519782
283 + 519499 = 519782
349 + 519433 = 519782
409 + 519373 = 519782

Showing the first eight; more decompositions exist.
