Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15970, here are decompositions:

11 + 15959 = 15970
47 + 15923 = 15970
83 + 15887 = 15970
89 + 15881 = 15970
167 + 15803 = 15970
173 + 15797 = 15970
179 + 15791 = 15970
197 + 15773 = 15970

Showing the first eight; more decompositions exist.
