Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18206, here are decompositions:

7 + 18199 = 18206
37 + 18169 = 18206
73 + 18133 = 18206
79 + 18127 = 18206
109 + 18097 = 18206
157 + 18049 = 18206
163 + 18043 = 18206
193 + 18013 = 18206

Showing the first eight; more decompositions exist.
