Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18262, here are decompositions:

5 + 18257 = 18262
11 + 18251 = 18262
29 + 18233 = 18262
71 + 18191 = 18262
113 + 18149 = 18262
131 + 18131 = 18262
173 + 18089 = 18262
281 + 17981 = 18262

Showing the first eight; more decompositions exist.
