Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187948, here are decompositions:

17 + 187931 = 187948
41 + 187907 = 187948
71 + 187877 = 187948
197 + 187751 = 187948
227 + 187721 = 187948
311 + 187637 = 187948
317 + 187631 = 187948
389 + 187559 = 187948

Showing the first eight; more decompositions exist.
