Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18146, here are decompositions:

3 + 18143 = 18146
13 + 18133 = 18146
19 + 18127 = 18146
97 + 18049 = 18146
103 + 18043 = 18146
157 + 17989 = 18146
223 + 17923 = 18146
283 + 17863 = 18146

Showing the first eight; more decompositions exist.
