Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79790, here are decompositions:
- 13 + 79777 = 79790
- 97 + 79693 = 79790
- 103 + 79687 = 79790
- 157 + 79633 = 79790
- 163 + 79627 = 79790
- 181 + 79609 = 79790
- 211 + 79579 = 79790
- 229 + 79561 = 79790
Showing the first eight; more decompositions exist.
