Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42706, here are decompositions:
- 3 + 42703 = 42706
- 5 + 42701 = 42706
- 17 + 42689 = 42706
- 23 + 42683 = 42706
- 29 + 42677 = 42706
- 137 + 42569 = 42706
- 149 + 42557 = 42706
- 173 + 42533 = 42706
Showing the first eight; more decompositions exist.
