Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9992, here are decompositions:

19 + 9973 = 9992
43 + 9949 = 9992
61 + 9931 = 9992
109 + 9883 = 9992
163 + 9829 = 9992
181 + 9811 = 9992
211 + 9781 = 9992
223 + 9769 = 9992

Showing the first eight; more decompositions exist.
