Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22818, here are decompositions:
- 7 + 22811 = 22818
- 11 + 22807 = 22818
- 31 + 22787 = 22818
- 41 + 22777 = 22818
- 67 + 22751 = 22818
- 79 + 22739 = 22818
- 97 + 22721 = 22818
- 101 + 22717 = 22818
Showing the first eight; more decompositions exist.
