Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511256, here are decompositions:

13 + 511243 = 511256
19 + 511237 = 511256
43 + 511213 = 511256
79 + 511177 = 511256
103 + 511153 = 511256
199 + 511057 = 511256
223 + 511033 = 511256
313 + 510943 = 511256

Showing the first eight; more decompositions exist.
