Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3898, here are decompositions:
- 17 + 3881 = 3898
- 47 + 3851 = 3898
- 101 + 3797 = 3898
- 131 + 3767 = 3898
- 137 + 3761 = 3898
- 179 + 3719 = 3898
- 197 + 3701 = 3898
- 227 + 3671 = 3898
Showing the first eight; more decompositions exist.
