Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3188, here are decompositions:

7 + 3181 = 3188
19 + 3169 = 3188
67 + 3121 = 3188
79 + 3109 = 3188
109 + 3079 = 3188
127 + 3061 = 3188
139 + 3049 = 3188
151 + 3037 = 3188

Showing the first eight; more decompositions exist.
