Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40838, here are decompositions:
- 19 + 40819 = 40838
- 37 + 40801 = 40838
- 67 + 40771 = 40838
- 79 + 40759 = 40838
- 139 + 40699 = 40838
- 199 + 40639 = 40838
- 211 + 40627 = 40838
- 229 + 40609 = 40838
Showing the first eight; more decompositions exist.
