Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187354, here are decompositions:

5 + 187349 = 187354
17 + 187337 = 187354
131 + 187223 = 187354
137 + 187217 = 187354
173 + 187181 = 187354
191 + 187163 = 187354
227 + 187127 = 187354
263 + 187091 = 187354

Showing the first eight; more decompositions exist.
