Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164944, here are decompositions:
- 107 + 164837 = 164944
- 113 + 164831 = 164944
- 173 + 164771 = 164944
- 281 + 164663 = 164944
- 317 + 164627 = 164944
- 431 + 164513 = 164944
- 467 + 164477 = 164944
- 557 + 164387 = 164944
Showing the first eight; more decompositions exist.
