Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9004, here are decompositions:
- 3 + 9001 = 9004
- 5 + 8999 = 9004
- 41 + 8963 = 9004
- 53 + 8951 = 9004
- 71 + 8933 = 9004
- 137 + 8867 = 9004
- 167 + 8837 = 9004
- 173 + 8831 = 9004
Showing the first eight; more decompositions exist.
