Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511608, here are decompositions:

5 + 511603 = 511608
17 + 511591 = 511608
29 + 511579 = 511608
59 + 511549 = 511608
67 + 511541 = 511608
89 + 511519 = 511608
101 + 511507 = 511608
131 + 511477 = 511608

Showing the first eight; more decompositions exist.
