Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511588, here are decompositions:

5 + 511583 = 511588
29 + 511559 = 511588
47 + 511541 = 511588
101 + 511487 = 511588
131 + 511457 = 511588
149 + 511439 = 511588
179 + 511409 = 511588
197 + 511391 = 511588

Showing the first eight; more decompositions exist.
