Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2160, here are decompositions:

7 + 2153 = 2160
17 + 2143 = 2160
19 + 2141 = 2160
23 + 2137 = 2160
29 + 2131 = 2160
31 + 2129 = 2160
47 + 2113 = 2160
61 + 2099 = 2160

Showing the first eight; more decompositions exist.
