Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9804, here are decompositions:

13 + 9791 = 9804
17 + 9787 = 9804
23 + 9781 = 9804
37 + 9767 = 9804
61 + 9743 = 9804
71 + 9733 = 9804
83 + 9721 = 9804
107 + 9697 = 9804

Showing the first eight; more decompositions exist.
