Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75724, here are decompositions:
- 3 + 75721 = 75724
- 17 + 75707 = 75724
- 41 + 75683 = 75724
- 71 + 75653 = 75724
- 83 + 75641 = 75724
- 107 + 75617 = 75724
- 113 + 75611 = 75724
- 167 + 75557 = 75724
Showing the first eight; more decompositions exist.
