Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18236, here are decompositions:

3 + 18233 = 18236
7 + 18229 = 18236
13 + 18223 = 18236
19 + 18217 = 18236
37 + 18199 = 18236
67 + 18169 = 18236
103 + 18133 = 18236
109 + 18127 = 18236

Showing the first eight; more decompositions exist.
