Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143866, here are decompositions:
- 53 + 143813 = 143866
- 59 + 143807 = 143866
- 137 + 143729 = 143866
- 167 + 143699 = 143866
- 179 + 143687 = 143866
- 197 + 143669 = 143866
- 257 + 143609 = 143866
- 293 + 143573 = 143866
Showing the first eight; more decompositions exist.
