Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18136, here are decompositions:

3 + 18133 = 18136
5 + 18131 = 18136
17 + 18119 = 18136
47 + 18089 = 18136
59 + 18077 = 18136
89 + 18047 = 18136
149 + 17987 = 18136
179 + 17957 = 18136

Showing the first eight; more decompositions exist.
