Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40566, here are decompositions:
- 7 + 40559 = 40566
- 23 + 40543 = 40566
- 37 + 40529 = 40566
- 47 + 40519 = 40566
- 59 + 40507 = 40566
- 67 + 40499 = 40566
- 73 + 40493 = 40566
- 79 + 40487 = 40566
Showing the first eight; more decompositions exist.
