Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42606, here are decompositions:
- 17 + 42589 = 42606
- 29 + 42577 = 42606
- 37 + 42569 = 42606
- 73 + 42533 = 42606
- 97 + 42509 = 42606
- 107 + 42499 = 42606
- 139 + 42467 = 42606
- 149 + 42457 = 42606
Showing the first eight; more decompositions exist.
