Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78358, here are decompositions:
- 11 + 78347 = 78358
- 17 + 78341 = 78358
- 41 + 78317 = 78358
- 47 + 78311 = 78358
- 167 + 78191 = 78358
- 179 + 78179 = 78358
- 191 + 78167 = 78358
- 257 + 78101 = 78358
Showing the first eight; more decompositions exist.
