Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143986, here are decompositions:
- 5 + 143981 = 143986
- 107 + 143879 = 143986
- 113 + 143873 = 143986
- 173 + 143813 = 143986
- 179 + 143807 = 143986
- 257 + 143729 = 143986
- 317 + 143669 = 143986
- 419 + 143567 = 143986
Showing the first eight; more decompositions exist.
