Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140668, here are decompositions:
- 5 + 140663 = 140668
- 29 + 140639 = 140668
- 41 + 140627 = 140668
- 191 + 140477 = 140668
- 251 + 140417 = 140668
- 257 + 140411 = 140668
- 317 + 140351 = 140668
- 347 + 140321 = 140668
Showing the first eight; more decompositions exist.
