Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3936, here are decompositions:

5 + 3931 = 3936
7 + 3929 = 3936
13 + 3923 = 3936
17 + 3919 = 3936
19 + 3917 = 3936
29 + 3907 = 3936
47 + 3889 = 3936
59 + 3877 = 3936

Showing the first eight; more decompositions exist.
