Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78406, here are decompositions:
- 5 + 78401 = 78406
- 59 + 78347 = 78406
- 89 + 78317 = 78406
- 173 + 78233 = 78406
- 227 + 78179 = 78406
- 233 + 78173 = 78406
- 239 + 78167 = 78406
- 269 + 78137 = 78406
Showing the first eight; more decompositions exist.
