Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68700, here are decompositions:
- 13 + 68687 = 68700
- 17 + 68683 = 68700
- 31 + 68669 = 68700
- 41 + 68659 = 68700
- 61 + 68639 = 68700
- 67 + 68633 = 68700
- 89 + 68611 = 68700
- 103 + 68597 = 68700
Showing the first eight; more decompositions exist.
