Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187340, here are decompositions:

3 + 187337 = 187340
37 + 187303 = 187340
67 + 187273 = 187340
103 + 187237 = 187340
151 + 187189 = 187340
163 + 187177 = 187340
199 + 187141 = 187340
211 + 187129 = 187340

Showing the first eight; more decompositions exist.
