Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3230, here are decompositions:

13 + 3217 = 3230
43 + 3187 = 3230
61 + 3169 = 3230
67 + 3163 = 3230
109 + 3121 = 3230
151 + 3079 = 3230
163 + 3067 = 3230
181 + 3049 = 3230

Showing the first eight; more decompositions exist.
