Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512288, here are decompositions:

19 + 512269 = 512288
37 + 512251 = 512288
151 + 512137 = 512288
229 + 512059 = 512288
241 + 512047 = 512288
277 + 512011 = 512288
349 + 511939 = 512288
379 + 511909 = 512288

Showing the first eight; more decompositions exist.
