Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78418, here are decompositions:
- 17 + 78401 = 78418
- 71 + 78347 = 78418
- 101 + 78317 = 78418
- 107 + 78311 = 78418
- 227 + 78191 = 78418
- 239 + 78179 = 78418
- 251 + 78167 = 78418
- 281 + 78137 = 78418
Showing the first eight; more decompositions exist.
