Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143122, here are decompositions:
- 11 + 143111 = 143122
- 29 + 143093 = 143122
- 59 + 143063 = 143122
- 149 + 142973 = 143122
- 173 + 142949 = 143122
- 251 + 142871 = 143122
- 281 + 142841 = 143122
- 311 + 142811 = 143122
Showing the first eight; more decompositions exist.
