Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3896, here are decompositions:

7 + 3889 = 3896
19 + 3877 = 3896
43 + 3853 = 3896
73 + 3823 = 3896
103 + 3793 = 3896
127 + 3769 = 3896
157 + 3739 = 3896
163 + 3733 = 3896

Showing the first eight; more decompositions exist.
