Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9808, here are decompositions:

5 + 9803 = 9808
17 + 9791 = 9808
41 + 9767 = 9808
59 + 9749 = 9808
89 + 9719 = 9808
131 + 9677 = 9808
179 + 9629 = 9808
257 + 9551 = 9808

Showing the first eight; more decompositions exist.
