Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189876, here are decompositions:

17 + 189859 = 189876
23 + 189853 = 189876
53 + 189823 = 189876
59 + 189817 = 189876
79 + 189797 = 189876
109 + 189767 = 189876
163 + 189713 = 189876
179 + 189697 = 189876

Showing the first eight; more decompositions exist.
