Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3158, here are decompositions:

37 + 3121 = 3158
79 + 3079 = 3158
97 + 3061 = 3158
109 + 3049 = 3158
139 + 3019 = 3158
157 + 3001 = 3158
241 + 2917 = 3158
271 + 2887 = 3158

Showing the first eight; more decompositions exist.
