Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143208, here are decompositions:
- 11 + 143197 = 143208
- 31 + 143177 = 143208
- 67 + 143141 = 143208
- 71 + 143137 = 143208
- 97 + 143111 = 143208
- 101 + 143107 = 143208
- 227 + 142981 = 143208
- 229 + 142979 = 143208
Showing the first eight; more decompositions exist.
