Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140686, here are decompositions:
- 3 + 140683 = 140686
- 5 + 140681 = 140686
- 23 + 140663 = 140686
- 47 + 140639 = 140686
- 59 + 140627 = 140686
- 83 + 140603 = 140686
- 137 + 140549 = 140686
- 233 + 140453 = 140686
Showing the first eight; more decompositions exist.
