Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140902, here are decompositions:
- 5 + 140897 = 140902
- 11 + 140891 = 140902
- 71 + 140831 = 140902
- 89 + 140813 = 140902
- 173 + 140729 = 140902
- 239 + 140663 = 140902
- 263 + 140639 = 140902
- 353 + 140549 = 140902
Showing the first eight; more decompositions exist.
