Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143272, here are decompositions:
- 11 + 143261 = 143272
- 23 + 143249 = 143272
- 29 + 143243 = 143272
- 113 + 143159 = 143272
- 131 + 143141 = 143272
- 179 + 143093 = 143272
- 293 + 142979 = 143272
- 401 + 142871 = 143272
Showing the first eight; more decompositions exist.
