Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15996, here are decompositions:

5 + 15991 = 15996
23 + 15973 = 15996
37 + 15959 = 15996
59 + 15937 = 15996
73 + 15923 = 15996
83 + 15913 = 15996
89 + 15907 = 15996
107 + 15889 = 15996

Showing the first eight; more decompositions exist.
