Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18314, here are decompositions:

3 + 18311 = 18314
7 + 18307 = 18314
13 + 18301 = 18314
61 + 18253 = 18314
97 + 18217 = 18314
103 + 18211 = 18314
181 + 18133 = 18314
193 + 18121 = 18314

Showing the first eight; more decompositions exist.
