Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9846, here are decompositions:

7 + 9839 = 9846
13 + 9833 = 9846
17 + 9829 = 9846
29 + 9817 = 9846
43 + 9803 = 9846
59 + 9787 = 9846
79 + 9767 = 9846
97 + 9749 = 9846

Showing the first eight; more decompositions exist.
