Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2176, here are decompositions:

23 + 2153 = 2176
47 + 2129 = 2176
89 + 2087 = 2176
107 + 2069 = 2176
113 + 2063 = 2176
137 + 2039 = 2176
149 + 2027 = 2176
173 + 2003 = 2176

Showing the first eight; more decompositions exist.
