Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78256, here are decompositions:
- 23 + 78233 = 78256
- 53 + 78203 = 78256
- 83 + 78173 = 78256
- 89 + 78167 = 78256
- 197 + 78059 = 78256
- 239 + 78017 = 78256
- 257 + 77999 = 78256
- 389 + 77867 = 78256
Showing the first eight; more decompositions exist.
