Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189828, here are decompositions:

5 + 189823 = 189828
11 + 189817 = 189828
29 + 189799 = 189828
31 + 189797 = 189828
61 + 189767 = 189828
71 + 189757 = 189828
127 + 189701 = 189828
131 + 189697 = 189828

Showing the first eight; more decompositions exist.
