Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40512, here are decompositions:
- 5 + 40507 = 40512
- 13 + 40499 = 40512
- 19 + 40493 = 40512
- 29 + 40483 = 40512
- 41 + 40471 = 40512
- 53 + 40459 = 40512
- 79 + 40433 = 40512
- 83 + 40429 = 40512
Showing the first eight; more decompositions exist.
