Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9008, here are decompositions:

7 + 9001 = 9008
37 + 8971 = 9008
67 + 8941 = 9008
79 + 8929 = 9008
229 + 8779 = 9008
271 + 8737 = 9008
277 + 8731 = 9008
331 + 8677 = 9008

Showing the first eight; more decompositions exist.
