Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42726, here are decompositions:
- 7 + 42719 = 42726
- 17 + 42709 = 42726
- 23 + 42703 = 42726
- 29 + 42697 = 42726
- 37 + 42689 = 42726
- 43 + 42683 = 42726
- 59 + 42667 = 42726
- 83 + 42643 = 42726
Showing the first eight; more decompositions exist.
