Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140644, here are decompositions:
- 5 + 140639 = 140644
- 17 + 140627 = 140644
- 41 + 140603 = 140644
- 167 + 140477 = 140644
- 191 + 140453 = 140644
- 227 + 140417 = 140644
- 233 + 140411 = 140644
- 263 + 140381 = 140644
Showing the first eight; more decompositions exist.
