Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511510, here are decompositions:

3 + 511507 = 511510
23 + 511487 = 511510
47 + 511463 = 511510
53 + 511457 = 511510
71 + 511439 = 511510
101 + 511409 = 511510
149 + 511361 = 511510
173 + 511337 = 511510

Showing the first eight; more decompositions exist.
