Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519398, here are decompositions:

7 + 519391 = 519398
97 + 519301 = 519398
151 + 519247 = 519398
181 + 519217 = 519398
277 + 519121 = 519398
307 + 519091 = 519398
331 + 519067 = 519398
367 + 519031 = 519398

Showing the first eight; more decompositions exist.
