Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15936, here are decompositions:

13 + 15923 = 15936
17 + 15919 = 15936
23 + 15913 = 15936
29 + 15907 = 15936
47 + 15889 = 15936
59 + 15877 = 15936
113 + 15823 = 15936
127 + 15809 = 15936

Showing the first eight; more decompositions exist.
