Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519908, here are decompositions:

19 + 519889 = 519908
139 + 519769 = 519908
241 + 519667 = 519908
331 + 519577 = 519908
409 + 519499 = 519908
421 + 519487 = 519908
601 + 519307 = 519908
607 + 519301 = 519908

Showing the first eight; more decompositions exist.
