Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3138, here are decompositions:

17 + 3121 = 3138
19 + 3119 = 3138
29 + 3109 = 3138
59 + 3079 = 3138
71 + 3067 = 3138
89 + 3049 = 3138
97 + 3041 = 3138
101 + 3037 = 3138

Showing the first eight; more decompositions exist.
