Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40558, here are decompositions:
- 29 + 40529 = 40558
- 59 + 40499 = 40558
- 71 + 40487 = 40558
- 131 + 40427 = 40558
- 197 + 40361 = 40558
- 269 + 40289 = 40558
- 281 + 40277 = 40558
- 317 + 40241 = 40558
Showing the first eight; more decompositions exist.
