Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12916, here are decompositions:

5 + 12911 = 12916
17 + 12899 = 12916
23 + 12893 = 12916
107 + 12809 = 12916
173 + 12743 = 12916
227 + 12689 = 12916
257 + 12659 = 12916
263 + 12653 = 12916

Showing the first eight; more decompositions exist.
