Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533994, here are decompositions:
- 71 + 31533923 = 31533994
- 83 + 31533911 = 31533994
- 353 + 31533641 = 31533994
- 383 + 31533611 = 31533994
- 431 + 31533563 = 31533994
- 461 + 31533533 = 31533994
- 563 + 31533431 = 31533994
- 827 + 31533167 = 31533994
Showing the first eight; more decompositions exist.
