Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40800, here are decompositions:
- 13 + 40787 = 40800
- 29 + 40771 = 40800
- 37 + 40763 = 40800
- 41 + 40759 = 40800
- 61 + 40739 = 40800
- 101 + 40699 = 40800
- 103 + 40697 = 40800
- 107 + 40693 = 40800
Showing the first eight; more decompositions exist.
