Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 566646, here are decompositions:

7 + 566639 = 566646
13 + 566633 = 566646
29 + 566617 = 566646
79 + 566567 = 566646
83 + 566563 = 566646
89 + 566557 = 566646
97 + 566549 = 566646
103 + 566543 = 566646

Showing the first eight; more decompositions exist.
