Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15676, here are decompositions:

5 + 15671 = 15676
29 + 15647 = 15676
47 + 15629 = 15676
107 + 15569 = 15676
149 + 15527 = 15676
179 + 15497 = 15676
233 + 15443 = 15676
263 + 15413 = 15676

Showing the first eight; more decompositions exist.
