Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18082, here are decompositions:

5 + 18077 = 18082
23 + 18059 = 18082
41 + 18041 = 18082
101 + 17981 = 18082
173 + 17909 = 18082
179 + 17903 = 18082
191 + 17891 = 18082
293 + 17789 = 18082

Showing the first eight; more decompositions exist.
