Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143200, here are decompositions:
- 3 + 143197 = 143200
- 23 + 143177 = 143200
- 41 + 143159 = 143200
- 59 + 143141 = 143200
- 89 + 143111 = 143200
- 107 + 143093 = 143200
- 137 + 143063 = 143200
- 227 + 142973 = 143200
Showing the first eight; more decompositions exist.
