Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40806, here are decompositions:
- 5 + 40801 = 40806
- 19 + 40787 = 40806
- 43 + 40763 = 40806
- 47 + 40759 = 40806
- 67 + 40739 = 40806
- 97 + 40709 = 40806
- 107 + 40699 = 40806
- 109 + 40697 = 40806
Showing the first eight; more decompositions exist.
