Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15598, here are decompositions:

17 + 15581 = 15598
29 + 15569 = 15598
47 + 15551 = 15598
71 + 15527 = 15598
101 + 15497 = 15598
131 + 15467 = 15598
137 + 15461 = 15598
197 + 15401 = 15598

Showing the first eight; more decompositions exist.
