Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9858, here are decompositions:

7 + 9851 = 9858
19 + 9839 = 9858
29 + 9829 = 9858
41 + 9817 = 9858
47 + 9811 = 9858
67 + 9791 = 9858
71 + 9787 = 9858
89 + 9769 = 9858

Showing the first eight; more decompositions exist.
