Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18182, here are decompositions:

13 + 18169 = 18182
61 + 18121 = 18182
139 + 18043 = 18182
193 + 17989 = 18182
211 + 17971 = 18182
223 + 17959 = 18182
271 + 17911 = 18182
331 + 17851 = 18182

Showing the first eight; more decompositions exist.
