Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8808, here are decompositions:
- 5 + 8803 = 8808
- 29 + 8779 = 8808
- 47 + 8761 = 8808
- 61 + 8747 = 8808
- 67 + 8741 = 8808
- 71 + 8737 = 8808
- 89 + 8719 = 8808
- 101 + 8707 = 8808
Showing the first eight; more decompositions exist.
