Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519928, here are decompositions:

5 + 519923 = 519928
11 + 519917 = 519928
47 + 519881 = 519928
131 + 519797 = 519928
191 + 519737 = 519928
281 + 519647 = 519928
317 + 519611 = 519928
347 + 519581 = 519928

Showing the first eight; more decompositions exist.
