Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78300, here are decompositions:
- 17 + 78283 = 78300
- 23 + 78277 = 78300
- 41 + 78259 = 78300
- 59 + 78241 = 78300
- 67 + 78233 = 78300
- 71 + 78229 = 78300
- 97 + 78203 = 78300
- 107 + 78193 = 78300
Showing the first eight; more decompositions exist.
