Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164164, here are decompositions:
- 17 + 164147 = 164164
- 47 + 164117 = 164164
- 71 + 164093 = 164164
- 107 + 164057 = 164164
- 113 + 164051 = 164164
- 167 + 163997 = 164164
- 173 + 163991 = 164164
- 191 + 163973 = 164164
Showing the first eight; more decompositions exist.
