Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519638, here are decompositions:

19 + 519619 = 519638
61 + 519577 = 519638
139 + 519499 = 519638
151 + 519487 = 519638
181 + 519457 = 519638
211 + 519427 = 519638
331 + 519307 = 519638
337 + 519301 = 519638

Showing the first eight; more decompositions exist.
