Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187732, here are decompositions:

11 + 187721 = 187732
71 + 187661 = 187732
101 + 187631 = 187732
173 + 187559 = 187732
263 + 187469 = 187732
269 + 187463 = 187732
353 + 187379 = 187732
359 + 187373 = 187732

Showing the first eight; more decompositions exist.
