Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4168, here are decompositions:
- 11 + 4157 = 4168
- 29 + 4139 = 4168
- 41 + 4127 = 4168
- 89 + 4079 = 4168
- 149 + 4019 = 4168
- 167 + 4001 = 4168
- 179 + 3989 = 4168
- 239 + 3929 = 4168
Showing the first eight; more decompositions exist.
