Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143254, here are decompositions:
- 5 + 143249 = 143254
- 11 + 143243 = 143254
- 113 + 143141 = 143254
- 191 + 143063 = 143254
- 281 + 142973 = 143254
- 347 + 142907 = 143254
- 383 + 142871 = 143254
- 443 + 142811 = 143254
Showing the first eight; more decompositions exist.
