Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18234, here are decompositions:

5 + 18229 = 18234
11 + 18223 = 18234
17 + 18217 = 18234
23 + 18211 = 18234
43 + 18191 = 18234
53 + 18181 = 18234
101 + 18133 = 18234
103 + 18131 = 18234

Showing the first eight; more decompositions exist.
