Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164772, here are decompositions:
- 5 + 164767 = 164772
- 29 + 164743 = 164772
- 43 + 164729 = 164772
- 71 + 164701 = 164772
- 89 + 164683 = 164772
- 109 + 164663 = 164772
- 149 + 164623 = 164772
- 151 + 164621 = 164772
Showing the first eight; more decompositions exist.
