Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519788, here are decompositions:

19 + 519769 = 519788
97 + 519691 = 519788
211 + 519577 = 519788
331 + 519457 = 519788
397 + 519391 = 519788
439 + 519349 = 519788
487 + 519301 = 519788
541 + 519247 = 519788

Showing the first eight; more decompositions exist.
