Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187834, here are decompositions:

11 + 187823 = 187834
41 + 187793 = 187834
47 + 187787 = 187834
71 + 187763 = 187834
83 + 187751 = 187834
113 + 187721 = 187834
173 + 187661 = 187834
197 + 187637 = 187834

Showing the first eight; more decompositions exist.
