Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143920, here are decompositions:
- 11 + 143909 = 143920
- 41 + 143879 = 143920
- 47 + 143873 = 143920
- 89 + 143831 = 143920
- 107 + 143813 = 143920
- 113 + 143807 = 143920
- 191 + 143729 = 143920
- 233 + 143687 = 143920
Showing the first eight; more decompositions exist.
