Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18598, here are decompositions:

5 + 18593 = 18598
11 + 18587 = 18598
59 + 18539 = 18598
137 + 18461 = 18598
197 + 18401 = 18598
227 + 18371 = 18598
257 + 18341 = 18598
269 + 18329 = 18598

Showing the first eight; more decompositions exist.
