Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25668, here are decompositions:
- 11 + 25657 = 25668
- 29 + 25639 = 25668
- 47 + 25621 = 25668
- 59 + 25609 = 25668
- 67 + 25601 = 25668
- 79 + 25589 = 25668
- 89 + 25579 = 25668
- 107 + 25561 = 25668
Showing the first eight; more decompositions exist.
