Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75742, here are decompositions:
- 11 + 75731 = 75742
- 53 + 75689 = 75742
- 59 + 75683 = 75742
- 83 + 75659 = 75742
- 89 + 75653 = 75742
- 101 + 75641 = 75742
- 113 + 75629 = 75742
- 131 + 75611 = 75742
Showing the first eight; more decompositions exist.
