Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9882, here are decompositions:

11 + 9871 = 9882
23 + 9859 = 9882
31 + 9851 = 9882
43 + 9839 = 9882
53 + 9829 = 9882
71 + 9811 = 9882
79 + 9803 = 9882
101 + 9781 = 9882

Showing the first eight; more decompositions exist.
