Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15358, here are decompositions:

29 + 15329 = 15358
59 + 15299 = 15358
71 + 15287 = 15358
89 + 15269 = 15358
131 + 15227 = 15358
197 + 15161 = 15358
227 + 15131 = 15358
251 + 15107 = 15358

Showing the first eight; more decompositions exist.
