Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511358, here are decompositions:

7 + 511351 = 511358
31 + 511327 = 511358
61 + 511297 = 511358
79 + 511279 = 511358
97 + 511261 = 511358
157 + 511201 = 511358
181 + 511177 = 511358
271 + 511087 = 511358

Showing the first eight; more decompositions exist.
