Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40568, here are decompositions:
- 37 + 40531 = 40568
- 61 + 40507 = 40568
- 97 + 40471 = 40568
- 109 + 40459 = 40568
- 139 + 40429 = 40568
- 181 + 40387 = 40568
- 211 + 40357 = 40568
- 331 + 40237 = 40568
Showing the first eight; more decompositions exist.
