Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8904, here are decompositions:
- 11 + 8893 = 8904
- 17 + 8887 = 8904
- 37 + 8867 = 8904
- 41 + 8863 = 8904
- 43 + 8861 = 8904
- 67 + 8837 = 8904
- 73 + 8831 = 8904
- 83 + 8821 = 8904
Showing the first eight; more decompositions exist.
