Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9822, here are decompositions:

5 + 9817 = 9822
11 + 9811 = 9822
19 + 9803 = 9822
31 + 9791 = 9822
41 + 9781 = 9822
53 + 9769 = 9822
73 + 9749 = 9822
79 + 9743 = 9822

Showing the first eight; more decompositions exist.
