Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143818, here are decompositions:
- 5 + 143813 = 143818
- 11 + 143807 = 143818
- 89 + 143729 = 143818
- 107 + 143711 = 143818
- 131 + 143687 = 143818
- 149 + 143669 = 143818
- 167 + 143651 = 143818
- 251 + 143567 = 143818
Showing the first eight; more decompositions exist.
