Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187328, here are decompositions:

109 + 187219 = 187328
139 + 187189 = 187328
151 + 187177 = 187328
157 + 187171 = 187328
199 + 187129 = 187328
439 + 186889 = 187328
457 + 186871 = 187328
487 + 186841 = 187328

Showing the first eight; more decompositions exist.
