Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17916, here are decompositions:

5 + 17911 = 17916
7 + 17909 = 17916
13 + 17903 = 17916
53 + 17863 = 17916
79 + 17837 = 17916
89 + 17827 = 17916
109 + 17807 = 17916
127 + 17789 = 17916

Showing the first eight; more decompositions exist.
