Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519604, here are decompositions:

17 + 519587 = 519604
23 + 519581 = 519604
53 + 519551 = 519604
83 + 519521 = 519604
191 + 519413 = 519604
233 + 519371 = 519604
251 + 519353 = 519604
317 + 519287 = 519604

Showing the first eight; more decompositions exist.
