Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3186, here are decompositions:

5 + 3181 = 3186
17 + 3169 = 3186
19 + 3167 = 3186
23 + 3163 = 3186
67 + 3119 = 3186
97 + 3089 = 3186
103 + 3083 = 3186
107 + 3079 = 3186

Showing the first eight; more decompositions exist.
