Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64168, here are decompositions:
- 11 + 64157 = 64168
- 17 + 64151 = 64168
- 59 + 64109 = 64168
- 101 + 64067 = 64168
- 131 + 64037 = 64168
- 149 + 64019 = 64168
- 191 + 63977 = 64168
- 239 + 63929 = 64168
Showing the first eight; more decompositions exist.
