Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3112, here are decompositions:

3 + 3109 = 3112
23 + 3089 = 3112
29 + 3083 = 3112
71 + 3041 = 3112
89 + 3023 = 3112
101 + 3011 = 3112
113 + 2999 = 3112
149 + 2963 = 3112

Showing the first eight; more decompositions exist.
