Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164724, here are decompositions:
- 17 + 164707 = 164724
- 23 + 164701 = 164724
- 41 + 164683 = 164724
- 47 + 164677 = 164724
- 61 + 164663 = 164724
- 71 + 164653 = 164724
- 97 + 164627 = 164724
- 101 + 164623 = 164724
Showing the first eight; more decompositions exist.
