Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517644, here are decompositions:

5 + 517639 = 517644
7 + 517637 = 517644
31 + 517613 = 517644
41 + 517603 = 517644
47 + 517597 = 517644
67 + 517577 = 517644
73 + 517571 = 517644
97 + 517547 = 517644

Showing the first eight; more decompositions exist.
