Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 566660, here are decompositions:

7 + 566653 = 566660
43 + 566617 = 566660
97 + 566563 = 566660
103 + 566557 = 566660
109 + 566551 = 566660
139 + 566521 = 566660
223 + 566437 = 566660
229 + 566431 = 566660

Showing the first eight; more decompositions exist.
