Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82644, here are decompositions:
- 11 + 82633 = 82644
- 31 + 82613 = 82644
- 43 + 82601 = 82644
- 53 + 82591 = 82644
- 73 + 82571 = 82644
- 83 + 82561 = 82644
- 113 + 82531 = 82644
- 137 + 82507 = 82644
Showing the first eight; more decompositions exist.
