Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140920, here are decompositions:
- 11 + 140909 = 140920
- 23 + 140897 = 140920
- 29 + 140891 = 140920
- 53 + 140867 = 140920
- 83 + 140837 = 140920
- 89 + 140831 = 140920
- 107 + 140813 = 140920
- 179 + 140741 = 140920
Showing the first eight; more decompositions exist.
