Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20758, here are decompositions:
- 5 + 20753 = 20758
- 11 + 20747 = 20758
- 41 + 20717 = 20758
- 131 + 20627 = 20758
- 251 + 20507 = 20758
- 281 + 20477 = 20758
- 317 + 20441 = 20758
- 347 + 20411 = 20758
Showing the first eight; more decompositions exist.
