Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9886, here are decompositions:

3 + 9883 = 9886
29 + 9857 = 9886
47 + 9839 = 9886
53 + 9833 = 9886
83 + 9803 = 9886
137 + 9749 = 9886
167 + 9719 = 9886
197 + 9689 = 9886

Showing the first eight; more decompositions exist.
