Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3216, here are decompositions:

7 + 3209 = 3216
13 + 3203 = 3216
29 + 3187 = 3216
47 + 3169 = 3216
53 + 3163 = 3216
79 + 3137 = 3216
97 + 3119 = 3216
107 + 3109 = 3216

Showing the first eight; more decompositions exist.
