Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164808, here are decompositions:
- 19 + 164789 = 164808
- 37 + 164771 = 164808
- 41 + 164767 = 164808
- 79 + 164729 = 164808
- 101 + 164707 = 164808
- 107 + 164701 = 164808
- 131 + 164677 = 164808
- 181 + 164627 = 164808
Showing the first eight; more decompositions exist.
