Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187384, here are decompositions:

5 + 187379 = 187384
11 + 187373 = 187384
17 + 187367 = 187384
23 + 187361 = 187384
47 + 187337 = 187384
107 + 187277 = 187384
167 + 187217 = 187384
173 + 187211 = 187384

Showing the first eight; more decompositions exist.
