Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40898, here are decompositions:
- 19 + 40879 = 40898
- 31 + 40867 = 40898
- 79 + 40819 = 40898
- 97 + 40801 = 40898
- 127 + 40771 = 40898
- 139 + 40759 = 40898
- 199 + 40699 = 40898
- 271 + 40627 = 40898
Showing the first eight; more decompositions exist.
