Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68500, here are decompositions:
- 11 + 68489 = 68500
- 17 + 68483 = 68500
- 23 + 68477 = 68500
- 53 + 68447 = 68500
- 101 + 68399 = 68500
- 149 + 68351 = 68500
- 239 + 68261 = 68500
- 281 + 68219 = 68500
Showing the first eight; more decompositions exist.
