Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78868, here are decompositions:
- 11 + 78857 = 78868
- 29 + 78839 = 78868
- 59 + 78809 = 78868
- 71 + 78797 = 78868
- 89 + 78779 = 78868
- 131 + 78737 = 78868
- 359 + 78509 = 78868
- 389 + 78479 = 78868
Showing the first eight; more decompositions exist.
