Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16590, here are decompositions:
- 17 + 16573 = 16590
- 23 + 16567 = 16590
- 29 + 16561 = 16590
- 37 + 16553 = 16590
- 43 + 16547 = 16590
- 61 + 16529 = 16590
- 71 + 16519 = 16590
- 97 + 16493 = 16590
Showing the first eight; more decompositions exist.
