Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17686, here are decompositions:

3 + 17683 = 17686
5 + 17681 = 17686
17 + 17669 = 17686
29 + 17657 = 17686
59 + 17627 = 17686
89 + 17597 = 17686
107 + 17579 = 17686
113 + 17573 = 17686

Showing the first eight; more decompositions exist.
