Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519404, here are decompositions:

13 + 519391 = 519404
31 + 519373 = 519404
97 + 519307 = 519404
103 + 519301 = 519404
157 + 519247 = 519404
211 + 519193 = 519404
283 + 519121 = 519404
307 + 519097 = 519404

Showing the first eight; more decompositions exist.
