Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3782, here are decompositions:
- 3 + 3779 = 3782
- 13 + 3769 = 3782
- 43 + 3739 = 3782
- 73 + 3709 = 3782
- 109 + 3673 = 3782
- 139 + 3643 = 3782
- 151 + 3631 = 3782
- 199 + 3583 = 3782
Showing the first eight; more decompositions exist.
