Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23818, here are decompositions:
- 5 + 23813 = 23818
- 17 + 23801 = 23818
- 29 + 23789 = 23818
- 71 + 23747 = 23818
- 131 + 23687 = 23818
- 149 + 23669 = 23818
- 191 + 23627 = 23818
- 251 + 23567 = 23818
Showing the first eight; more decompositions exist.
