Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18196, here are decompositions:

5 + 18191 = 18196
47 + 18149 = 18196
53 + 18143 = 18196
107 + 18089 = 18196
137 + 18059 = 18196
149 + 18047 = 18196
239 + 17957 = 18196
257 + 17939 = 18196

Showing the first eight; more decompositions exist.
