Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519844, here are decompositions:

41 + 519803 = 519844
47 + 519797 = 519844
107 + 519737 = 519844
131 + 519713 = 519844
197 + 519647 = 519844
233 + 519611 = 519844
257 + 519587 = 519844
263 + 519581 = 519844

Showing the first eight; more decompositions exist.
