Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18130, here are decompositions:

3 + 18127 = 18130
11 + 18119 = 18130
41 + 18089 = 18130
53 + 18077 = 18130
71 + 18059 = 18130
83 + 18047 = 18130
89 + 18041 = 18130
149 + 17981 = 18130

Showing the first eight; more decompositions exist.
