Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3150, here are decompositions:

13 + 3137 = 3150
29 + 3121 = 3150
31 + 3119 = 3150
41 + 3109 = 3150
61 + 3089 = 3150
67 + 3083 = 3150
71 + 3079 = 3150
83 + 3067 = 3150

Showing the first eight; more decompositions exist.
