Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519288, here are decompositions:

5 + 519283 = 519288
19 + 519269 = 519288
31 + 519257 = 519288
41 + 519247 = 519288
59 + 519229 = 519288
61 + 519227 = 519288
71 + 519217 = 519288
127 + 519161 = 519288

Showing the first eight; more decompositions exist.
