Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15934, here are decompositions:

11 + 15923 = 15934
47 + 15887 = 15934
53 + 15881 = 15934
131 + 15803 = 15934
137 + 15797 = 15934
167 + 15767 = 15934
173 + 15761 = 15934
197 + 15737 = 15934

Showing the first eight; more decompositions exist.
