Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15508, here are decompositions:

11 + 15497 = 15508
41 + 15467 = 15508
47 + 15461 = 15508
107 + 15401 = 15508
131 + 15377 = 15508
149 + 15359 = 15508
179 + 15329 = 15508
239 + 15269 = 15508

Showing the first eight; more decompositions exist.
