Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511540, here are decompositions:

17 + 511523 = 511540
53 + 511487 = 511540
83 + 511457 = 511540
101 + 511439 = 511540
131 + 511409 = 511540
149 + 511391 = 511540
179 + 511361 = 511540
251 + 511289 = 511540

Showing the first eight; more decompositions exist.
