Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17666, here are decompositions:

7 + 17659 = 17666
43 + 17623 = 17666
67 + 17599 = 17666
97 + 17569 = 17666
127 + 17539 = 17666
157 + 17509 = 17666
199 + 17467 = 17666
223 + 17443 = 17666

Showing the first eight; more decompositions exist.
