Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187888, here are decompositions:

5 + 187883 = 187888
11 + 187877 = 187888
17 + 187871 = 187888
101 + 187787 = 187888
137 + 187751 = 187888
167 + 187721 = 187888
227 + 187661 = 187888
251 + 187637 = 187888

Showing the first eight; more decompositions exist.
