Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18116, here are decompositions:

19 + 18097 = 18116
67 + 18049 = 18116
73 + 18043 = 18116
103 + 18013 = 18116
127 + 17989 = 18116
139 + 17977 = 18116
157 + 17959 = 18116
193 + 17923 = 18116

Showing the first eight; more decompositions exist.
