Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78768, here are decompositions:
- 31 + 78737 = 78768
- 47 + 78721 = 78768
- 61 + 78707 = 78768
- 71 + 78697 = 78768
- 191 + 78577 = 78768
- 197 + 78571 = 78768
- 199 + 78569 = 78768
- 227 + 78541 = 78768
Showing the first eight; more decompositions exist.
