Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40584, here are decompositions:
- 7 + 40577 = 40584
- 41 + 40543 = 40584
- 53 + 40531 = 40584
- 97 + 40487 = 40584
- 101 + 40483 = 40584
- 113 + 40471 = 40584
- 151 + 40433 = 40584
- 157 + 40427 = 40584
Showing the first eight; more decompositions exist.
