Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519258, here are decompositions:

11 + 519247 = 519258
29 + 519229 = 519258
31 + 519227 = 519258
41 + 519217 = 519258
97 + 519161 = 519258
107 + 519151 = 519258
127 + 519131 = 519258
137 + 519121 = 519258

Showing the first eight; more decompositions exist.
