Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9856, here are decompositions:

5 + 9851 = 9856
17 + 9839 = 9856
23 + 9833 = 9856
53 + 9803 = 9856
89 + 9767 = 9856
107 + 9749 = 9856
113 + 9743 = 9856
137 + 9719 = 9856

Showing the first eight; more decompositions exist.
