Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519372, here are decompositions:

13 + 519359 = 519372
19 + 519353 = 519372
23 + 519349 = 519372
71 + 519301 = 519372
89 + 519283 = 519372
103 + 519269 = 519372
179 + 519193 = 519372
211 + 519161 = 519372

Showing the first eight; more decompositions exist.
