Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511616, here are decompositions:

13 + 511603 = 511616
37 + 511579 = 511616
43 + 511573 = 511616
67 + 511549 = 511616
97 + 511519 = 511616
109 + 511507 = 511616
139 + 511477 = 511616
163 + 511453 = 511616

Showing the first eight; more decompositions exist.
