Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9998, here are decompositions:

31 + 9967 = 9998
67 + 9931 = 9998
97 + 9901 = 9998
127 + 9871 = 9998
139 + 9859 = 9998
181 + 9817 = 9998
211 + 9787 = 9998
229 + 9769 = 9998

Showing the first eight; more decompositions exist.
