Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511560, here are decompositions:

11 + 511549 = 511560
19 + 511541 = 511560
37 + 511523 = 511560
41 + 511519 = 511560
53 + 511507 = 511560
73 + 511487 = 511560
83 + 511477 = 511560
97 + 511463 = 511560

Showing the first eight; more decompositions exist.
