Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3200, here are decompositions:

13 + 3187 = 3200
19 + 3181 = 3200
31 + 3169 = 3200
37 + 3163 = 3200
79 + 3121 = 3200
139 + 3061 = 3200
151 + 3049 = 3200
163 + 3037 = 3200

Showing the first eight; more decompositions exist.
