Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7666, here are decompositions:
- 17 + 7649 = 7666
- 23 + 7643 = 7666
- 59 + 7607 = 7666
- 83 + 7583 = 7666
- 89 + 7577 = 7666
- 107 + 7559 = 7666
- 137 + 7529 = 7666
- 149 + 7517 = 7666
Showing the first eight; more decompositions exist.
