Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40168, here are decompositions:
- 5 + 40163 = 40168
- 17 + 40151 = 40168
- 41 + 40127 = 40168
- 131 + 40037 = 40168
- 137 + 40031 = 40168
- 179 + 39989 = 40168
- 197 + 39971 = 40168
- 239 + 39929 = 40168
Showing the first eight; more decompositions exist.
