Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511494, here are decompositions:

7 + 511487 = 511494
17 + 511477 = 511494
31 + 511463 = 511494
37 + 511457 = 511494
41 + 511453 = 511494
47 + 511447 = 511494
103 + 511391 = 511494
107 + 511387 = 511494

Showing the first eight; more decompositions exist.
