Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519738, here are decompositions:

5 + 519733 = 519738
47 + 519691 = 519738
71 + 519667 = 519738
127 + 519611 = 519738
151 + 519587 = 519738
157 + 519581 = 519738
199 + 519539 = 519738
211 + 519527 = 519738

Showing the first eight; more decompositions exist.
