Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15502, here are decompositions:

5 + 15497 = 15502
29 + 15473 = 15502
41 + 15461 = 15502
59 + 15443 = 15502
89 + 15413 = 15502
101 + 15401 = 15502
173 + 15329 = 15502
233 + 15269 = 15502

Showing the first eight; more decompositions exist.
