Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15696, here are decompositions:

13 + 15683 = 15696
17 + 15679 = 15696
29 + 15667 = 15696
47 + 15649 = 15696
53 + 15643 = 15696
67 + 15629 = 15696
89 + 15607 = 15696
113 + 15583 = 15696

Showing the first eight; more decompositions exist.
