Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15994, here are decompositions:

3 + 15991 = 15994
23 + 15971 = 15994
71 + 15923 = 15994
107 + 15887 = 15994
113 + 15881 = 15994
191 + 15803 = 15994
197 + 15797 = 15994
227 + 15767 = 15994

Showing the first eight; more decompositions exist.
