Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40560, here are decompositions:
- 17 + 40543 = 40560
- 29 + 40531 = 40560
- 31 + 40529 = 40560
- 41 + 40519 = 40560
- 53 + 40507 = 40560
- 61 + 40499 = 40560
- 67 + 40493 = 40560
- 73 + 40487 = 40560
Showing the first eight; more decompositions exist.
