Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187322, here are decompositions:

19 + 187303 = 187322
103 + 187219 = 187322
151 + 187171 = 187322
181 + 187141 = 187322
193 + 187129 = 187322
199 + 187123 = 187322
211 + 187111 = 187322
241 + 187081 = 187322

Showing the first eight; more decompositions exist.
