Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3648, here are decompositions:
- 5 + 3643 = 3648
- 11 + 3637 = 3648
- 17 + 3631 = 3648
- 31 + 3617 = 3648
- 41 + 3607 = 3648
- 67 + 3581 = 3648
- 89 + 3559 = 3648
- 101 + 3547 = 3648
Showing the first eight; more decompositions exist.
