Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2116, here are decompositions:

3 + 2113 = 2116
5 + 2111 = 2116
17 + 2099 = 2116
29 + 2087 = 2116
47 + 2069 = 2116
53 + 2063 = 2116
89 + 2027 = 2116
113 + 2003 = 2116

Showing the first eight; more decompositions exist.
