Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511558, here are decompositions:

17 + 511541 = 511558
71 + 511487 = 511558
101 + 511457 = 511558
149 + 511409 = 511558
167 + 511391 = 511558
197 + 511361 = 511558
269 + 511289 = 511558
347 + 511211 = 511558

Showing the first eight; more decompositions exist.
