Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42164, here are decompositions:

7 + 42157 = 42164
103 + 42061 = 42164
151 + 42013 = 42164
181 + 41983 = 42164
211 + 41953 = 42164
223 + 41941 = 42164
271 + 41893 = 42164
277 + 41887 = 42164

Showing the first eight; more decompositions exist.
