Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68722, here are decompositions:
- 11 + 68711 = 68722
- 23 + 68699 = 68722
- 53 + 68669 = 68722
- 83 + 68639 = 68722
- 89 + 68633 = 68722
- 179 + 68543 = 68722
- 191 + 68531 = 68722
- 233 + 68489 = 68722
Showing the first eight; more decompositions exist.
