Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511268, here are decompositions:

7 + 511261 = 511268
31 + 511237 = 511268
67 + 511201 = 511268
97 + 511171 = 511268
157 + 511111 = 511268
181 + 511087 = 511268
211 + 511057 = 511268
229 + 511039 = 511268

Showing the first eight; more decompositions exist.
