Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143260, here are decompositions:
- 3 + 143257 = 143260
- 11 + 143249 = 143260
- 17 + 143243 = 143260
- 83 + 143177 = 143260
- 101 + 143159 = 143260
- 149 + 143111 = 143260
- 167 + 143093 = 143260
- 197 + 143063 = 143260
Showing the first eight; more decompositions exist.
