Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2170, here are decompositions:

17 + 2153 = 2170
29 + 2141 = 2170
41 + 2129 = 2170
59 + 2111 = 2170
71 + 2099 = 2170
83 + 2087 = 2170
89 + 2081 = 2170
101 + 2069 = 2170

Showing the first eight; more decompositions exist.
