Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519428, here are decompositions:

37 + 519391 = 519428
79 + 519349 = 519428
127 + 519301 = 519428
181 + 519247 = 519428
199 + 519229 = 519428
211 + 519217 = 519428
277 + 519151 = 519428
307 + 519121 = 519428

Showing the first eight; more decompositions exist.
