Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140866, here are decompositions:
- 3 + 140863 = 140866
- 29 + 140837 = 140866
- 53 + 140813 = 140866
- 107 + 140759 = 140866
- 137 + 140729 = 140866
- 149 + 140717 = 140866
- 227 + 140639 = 140866
- 239 + 140627 = 140866
Showing the first eight; more decompositions exist.
