Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42766, here are decompositions:
- 23 + 42743 = 42766
- 29 + 42737 = 42766
- 47 + 42719 = 42766
- 83 + 42683 = 42766
- 89 + 42677 = 42766
- 197 + 42569 = 42766
- 233 + 42533 = 42766
- 257 + 42509 = 42766
Showing the first eight; more decompositions exist.
