Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7178, here are decompositions:

19 + 7159 = 7178
109 + 7069 = 7178
139 + 7039 = 7178
151 + 7027 = 7178
181 + 6997 = 7178
211 + 6967 = 7178
229 + 6949 = 7178
271 + 6907 = 7178

Showing the first eight; more decompositions exist.
