Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512408, here are decompositions:

19 + 512389 = 512408
97 + 512311 = 512408
139 + 512269 = 512408
157 + 512251 = 512408
241 + 512167 = 512408
271 + 512137 = 512408
307 + 512101 = 512408
349 + 512059 = 512408

Showing the first eight; more decompositions exist.
