Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9936, here are decompositions:

5 + 9931 = 9936
7 + 9929 = 9936
13 + 9923 = 9936
29 + 9907 = 9936
53 + 9883 = 9936
79 + 9857 = 9936
97 + 9839 = 9936
103 + 9833 = 9936

Showing the first eight; more decompositions exist.
