Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40818, here are decompositions:
- 5 + 40813 = 40818
- 17 + 40801 = 40818
- 31 + 40787 = 40818
- 47 + 40771 = 40818
- 59 + 40759 = 40818
- 67 + 40751 = 40818
- 79 + 40739 = 40818
- 109 + 40709 = 40818
Showing the first eight; more decompositions exist.
