Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517648, here are decompositions:

11 + 517637 = 517648
29 + 517619 = 517648
59 + 517589 = 517648
71 + 517577 = 517648
101 + 517547 = 517648
137 + 517511 = 517648
149 + 517499 = 517648
167 + 517481 = 517648

Showing the first eight; more decompositions exist.
