Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18308, here are decompositions:

7 + 18301 = 18308
19 + 18289 = 18308
79 + 18229 = 18308
97 + 18211 = 18308
109 + 18199 = 18308
127 + 18181 = 18308
139 + 18169 = 18308
181 + 18127 = 18308

Showing the first eight; more decompositions exist.
