Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3842, here are decompositions:
- 19 + 3823 = 3842
- 73 + 3769 = 3842
- 103 + 3739 = 3842
- 109 + 3733 = 3842
- 151 + 3691 = 3842
- 199 + 3643 = 3842
- 211 + 3631 = 3842
- 229 + 3613 = 3842
Showing the first eight; more decompositions exist.
