Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3928, here are decompositions:

5 + 3923 = 3928
11 + 3917 = 3928
17 + 3911 = 3928
47 + 3881 = 3928
107 + 3821 = 3928
131 + 3797 = 3928
149 + 3779 = 3928
167 + 3761 = 3928

Showing the first eight; more decompositions exist.
