Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3130, here are decompositions:

11 + 3119 = 3130
41 + 3089 = 3130
47 + 3083 = 3130
89 + 3041 = 3130
107 + 3023 = 3130
131 + 2999 = 3130
167 + 2963 = 3130
173 + 2957 = 3130

Showing the first eight; more decompositions exist.
