Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20164, here are decompositions:
- 3 + 20161 = 20164
- 17 + 20147 = 20164
- 41 + 20123 = 20164
- 47 + 20117 = 20164
- 101 + 20063 = 20164
- 113 + 20051 = 20164
- 167 + 19997 = 20164
- 173 + 19991 = 20164
Showing the first eight; more decompositions exist.
