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.
