Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 566566, here are decompositions:

3 + 566563 = 566566
17 + 566549 = 566566
23 + 566543 = 566566
29 + 566537 = 566566
113 + 566453 = 566566
137 + 566429 = 566566
149 + 566417 = 566566
173 + 566393 = 566566

Showing the first eight; more decompositions exist.
