Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17724, here are decompositions:

11 + 17713 = 17724
17 + 17707 = 17724
41 + 17683 = 17724
43 + 17681 = 17724
67 + 17657 = 17724
97 + 17627 = 17724
101 + 17623 = 17724
127 + 17597 = 17724

Showing the first eight; more decompositions exist.
