Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3156, here are decompositions:

19 + 3137 = 3156
37 + 3119 = 3156
47 + 3109 = 3156
67 + 3089 = 3156
73 + 3083 = 3156
89 + 3067 = 3156
107 + 3049 = 3156
137 + 3019 = 3156

Showing the first eight; more decompositions exist.
