Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511584, here are decompositions:

5 + 511579 = 511584
11 + 511573 = 511584
43 + 511541 = 511584
61 + 511523 = 511584
97 + 511487 = 511584
107 + 511477 = 511584
127 + 511457 = 511584
131 + 511453 = 511584

Showing the first eight; more decompositions exist.
