Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18160, here are decompositions:

11 + 18149 = 18160
17 + 18143 = 18160
29 + 18131 = 18160
41 + 18119 = 18160
71 + 18089 = 18160
83 + 18077 = 18160
101 + 18059 = 18160
113 + 18047 = 18160

Showing the first eight; more decompositions exist.
