Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7160, here are decompositions:

31 + 7129 = 7160
103 + 7057 = 7160
163 + 6997 = 7160
193 + 6967 = 7160
199 + 6961 = 7160
211 + 6949 = 7160
277 + 6883 = 7160
331 + 6829 = 7160

Showing the first eight; more decompositions exist.
