Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511326, here are decompositions:

29 + 511297 = 511326
37 + 511289 = 511326
47 + 511279 = 511326
83 + 511243 = 511326
89 + 511237 = 511326
103 + 511223 = 511326
113 + 511213 = 511326
149 + 511177 = 511326

Showing the first eight; more decompositions exist.
