Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511298, here are decompositions:

19 + 511279 = 511298
37 + 511261 = 511298
61 + 511237 = 511298
97 + 511201 = 511298
127 + 511171 = 511298
211 + 511087 = 511298
241 + 511057 = 511298
367 + 510931 = 511298

Showing the first eight; more decompositions exist.
