Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 566740, here are decompositions:

3 + 566737 = 566740
17 + 566723 = 566740
23 + 566717 = 566740
47 + 566693 = 566740
59 + 566681 = 566740
101 + 566639 = 566740
107 + 566633 = 566740
173 + 566567 = 566740

Showing the first eight; more decompositions exist.
