Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 566664, here are decompositions:

5 + 566659 = 566664
11 + 566653 = 566664
31 + 566633 = 566664
47 + 566617 = 566664
97 + 566567 = 566664
101 + 566563 = 566664
107 + 566557 = 566664
113 + 566551 = 566664

Showing the first eight; more decompositions exist.
