Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143230, here are decompositions:
- 53 + 143177 = 143230
- 71 + 143159 = 143230
- 89 + 143141 = 143230
- 137 + 143093 = 143230
- 167 + 143063 = 143230
- 251 + 142979 = 143230
- 257 + 142973 = 143230
- 281 + 142949 = 143230
Showing the first eight; more decompositions exist.
