Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40500, here are decompositions:
- 7 + 40493 = 40500
- 13 + 40487 = 40500
- 17 + 40483 = 40500
- 29 + 40471 = 40500
- 41 + 40459 = 40500
- 67 + 40433 = 40500
- 71 + 40429 = 40500
- 73 + 40427 = 40500
Showing the first eight; more decompositions exist.
