Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519408, here are decompositions:

17 + 519391 = 519408
37 + 519371 = 519408
59 + 519349 = 519408
101 + 519307 = 519408
107 + 519301 = 519408
139 + 519269 = 519408
151 + 519257 = 519408
179 + 519229 = 519408

Showing the first eight; more decompositions exist.
