Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184210, here are decompositions:

11 + 184199 = 184210
23 + 184187 = 184210
29 + 184181 = 184210
53 + 184157 = 184210
137 + 184073 = 184210
167 + 184043 = 184210
179 + 184031 = 184210
197 + 184013 = 184210

Showing the first eight; more decompositions exist.
