Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519722, here are decompositions:

19 + 519703 = 519722
31 + 519691 = 519722
79 + 519643 = 519722
103 + 519619 = 519722
199 + 519523 = 519722
223 + 519499 = 519722
331 + 519391 = 519722
349 + 519373 = 519722

Showing the first eight; more decompositions exist.
