Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28306, here are decompositions:
- 17 + 28289 = 28306
- 23 + 28283 = 28306
- 29 + 28277 = 28306
- 197 + 28109 = 28306
- 353 + 27953 = 28306
- 359 + 27947 = 28306
- 389 + 27917 = 28306
- 479 + 27827 = 28306
Showing the first eight; more decompositions exist.
