Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2110, here are decompositions:

11 + 2099 = 2110
23 + 2087 = 2110
29 + 2081 = 2110
41 + 2069 = 2110
47 + 2063 = 2110
71 + 2039 = 2110
83 + 2027 = 2110
107 + 2003 = 2110

Showing the first eight; more decompositions exist.
