Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17966, here are decompositions:

7 + 17959 = 17966
37 + 17929 = 17966
43 + 17923 = 17966
103 + 17863 = 17966
127 + 17839 = 17966
139 + 17827 = 17966
229 + 17737 = 17966
283 + 17683 = 17966

Showing the first eight; more decompositions exist.
