Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519850, here are decompositions:

47 + 519803 = 519850
53 + 519797 = 519850
113 + 519737 = 519850
137 + 519713 = 519850
167 + 519683 = 519850
239 + 519611 = 519850
263 + 519587 = 519850
269 + 519581 = 519850

Showing the first eight; more decompositions exist.
