Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511536, here are decompositions:

13 + 511523 = 511536
17 + 511519 = 511536
29 + 511507 = 511536
59 + 511477 = 511536
73 + 511463 = 511536
79 + 511457 = 511536
83 + 511453 = 511536
89 + 511447 = 511536

Showing the first eight; more decompositions exist.
