Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15418, here are decompositions:

5 + 15413 = 15418
17 + 15401 = 15418
41 + 15377 = 15418
59 + 15359 = 15418
89 + 15329 = 15418
131 + 15287 = 15418
149 + 15269 = 15418
191 + 15227 = 15418

Showing the first eight; more decompositions exist.
