Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68670, here are decompositions:
- 11 + 68659 = 68670
- 31 + 68639 = 68670
- 37 + 68633 = 68670
- 59 + 68611 = 68670
- 73 + 68597 = 68670
- 89 + 68581 = 68670
- 103 + 68567 = 68670
- 127 + 68543 = 68670
Showing the first eight; more decompositions exist.
