Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40516, here are decompositions:
- 17 + 40499 = 40516
- 23 + 40493 = 40516
- 29 + 40487 = 40516
- 83 + 40433 = 40516
- 89 + 40427 = 40516
- 173 + 40343 = 40516
- 227 + 40289 = 40516
- 233 + 40283 = 40516
Showing the first eight; more decompositions exist.
