Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519340, here are decompositions:

53 + 519287 = 519340
71 + 519269 = 519340
83 + 519257 = 519340
113 + 519227 = 519340
179 + 519161 = 519340
233 + 519107 = 519340
251 + 519089 = 519340
257 + 519083 = 519340

Showing the first eight; more decompositions exist.
