Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511506, here are decompositions:

19 + 511487 = 511506
29 + 511477 = 511506
43 + 511463 = 511506
53 + 511453 = 511506
59 + 511447 = 511506
67 + 511439 = 511506
89 + 511417 = 511506
97 + 511409 = 511506

Showing the first eight; more decompositions exist.
