Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187876, here are decompositions:

5 + 187871 = 187876
53 + 187823 = 187876
83 + 187793 = 187876
89 + 187787 = 187876
113 + 187763 = 187876
239 + 187637 = 187876
317 + 187559 = 187876
443 + 187433 = 187876

Showing the first eight; more decompositions exist.
