Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511524, here are decompositions:

5 + 511519 = 511524
17 + 511507 = 511524
37 + 511487 = 511524
47 + 511477 = 511524
61 + 511463 = 511524
67 + 511457 = 511524
71 + 511453 = 511524
107 + 511417 = 511524

Showing the first eight; more decompositions exist.
