Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72164, here are decompositions:

3 + 72161 = 72164
61 + 72103 = 72164
73 + 72091 = 72164
181 + 71983 = 72164
193 + 71971 = 72164
223 + 71941 = 72164
277 + 71887 = 72164
283 + 71881 = 72164

Showing the first eight; more decompositions exist.
