Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3120, here are decompositions:

11 + 3109 = 3120
31 + 3089 = 3120
37 + 3083 = 3120
41 + 3079 = 3120
53 + 3067 = 3120
59 + 3061 = 3120
71 + 3049 = 3120
79 + 3041 = 3120

Showing the first eight; more decompositions exist.
