Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10818, here are decompositions:
- 19 + 10799 = 10818
- 29 + 10789 = 10818
- 37 + 10781 = 10818
- 47 + 10771 = 10818
- 79 + 10739 = 10818
- 89 + 10729 = 10818
- 107 + 10711 = 10818
- 109 + 10709 = 10818
Showing the first eight; more decompositions exist.
