Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519380, here are decompositions:

7 + 519373 = 519380
31 + 519349 = 519380
73 + 519307 = 519380
79 + 519301 = 519380
97 + 519283 = 519380
151 + 519229 = 519380
163 + 519217 = 519380
229 + 519151 = 519380

Showing the first eight; more decompositions exist.
