Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25768, here are decompositions:
- 5 + 25763 = 25768
- 89 + 25679 = 25768
- 101 + 25667 = 25768
- 167 + 25601 = 25768
- 179 + 25589 = 25768
- 191 + 25577 = 25768
- 227 + 25541 = 25768
- 311 + 25457 = 25768
Showing the first eight; more decompositions exist.
