Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19676, here are decompositions:
- 67 + 19609 = 19676
- 73 + 19603 = 19676
- 79 + 19597 = 19676
- 193 + 19483 = 19676
- 199 + 19477 = 19676
- 229 + 19447 = 19676
- 367 + 19309 = 19676
- 409 + 19267 = 19676
Showing the first eight; more decompositions exist.
