Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2164, here are decompositions:

3 + 2161 = 2164
11 + 2153 = 2164
23 + 2141 = 2164
53 + 2111 = 2164
83 + 2081 = 2164
101 + 2063 = 2164
137 + 2027 = 2164
167 + 1997 = 2164

Showing the first eight; more decompositions exist.
