Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90008, here are decompositions:

7 + 90001 = 90008
19 + 89989 = 90008
31 + 89977 = 90008
109 + 89899 = 90008
199 + 89809 = 90008
211 + 89797 = 90008
229 + 89779 = 90008
241 + 89767 = 90008

Showing the first eight; more decompositions exist.
