Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40816, here are decompositions:
- 3 + 40813 = 40816
- 29 + 40787 = 40816
- 53 + 40763 = 40816
- 107 + 40709 = 40816
- 179 + 40637 = 40816
- 233 + 40583 = 40816
- 239 + 40577 = 40816
- 257 + 40559 = 40816
Showing the first eight; more decompositions exist.
