Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3154, here are decompositions:

17 + 3137 = 3154
71 + 3083 = 3154
113 + 3041 = 3154
131 + 3023 = 3154
191 + 2963 = 3154
197 + 2957 = 3154
227 + 2927 = 3154
251 + 2903 = 3154

Showing the first eight; more decompositions exist.
