Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3100, here are decompositions:

11 + 3089 = 3100
17 + 3083 = 3100
59 + 3041 = 3100
89 + 3011 = 3100
101 + 2999 = 3100
131 + 2969 = 3100
137 + 2963 = 3100
173 + 2927 = 3100

Showing the first eight; more decompositions exist.
