Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78340, here are decompositions:
- 23 + 78317 = 78340
- 29 + 78311 = 78340
- 107 + 78233 = 78340
- 137 + 78203 = 78340
- 149 + 78191 = 78340
- 167 + 78173 = 78340
- 173 + 78167 = 78340
- 239 + 78101 = 78340
Showing the first eight; more decompositions exist.
