Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18210, here are decompositions:

11 + 18199 = 18210
19 + 18191 = 18210
29 + 18181 = 18210
41 + 18169 = 18210
61 + 18149 = 18210
67 + 18143 = 18210
79 + 18131 = 18210
83 + 18127 = 18210

Showing the first eight; more decompositions exist.
