Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15898, here are decompositions:

11 + 15887 = 15898
17 + 15881 = 15898
89 + 15809 = 15898
101 + 15797 = 15898
107 + 15791 = 15898
131 + 15767 = 15898
137 + 15761 = 15898
149 + 15749 = 15898

Showing the first eight; more decompositions exist.
