Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15888, here are decompositions:

7 + 15881 = 15888
11 + 15877 = 15888
29 + 15859 = 15888
71 + 15817 = 15888
79 + 15809 = 15888
97 + 15791 = 15888
101 + 15787 = 15888
127 + 15761 = 15888

Showing the first eight; more decompositions exist.
