Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68778, here are decompositions:
- 7 + 68771 = 68778
- 11 + 68767 = 68778
- 29 + 68749 = 68778
- 41 + 68737 = 68778
- 67 + 68711 = 68778
- 79 + 68699 = 68778
- 109 + 68669 = 68778
- 139 + 68639 = 68778
Showing the first eight; more decompositions exist.
