Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9006, here are decompositions:

5 + 9001 = 9006
7 + 8999 = 9006
37 + 8969 = 9006
43 + 8963 = 9006
73 + 8933 = 9006
83 + 8923 = 9006
113 + 8893 = 9006
139 + 8867 = 9006

Showing the first eight; more decompositions exist.
