Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18922, here are decompositions:
- 3 + 18919 = 18922
- 5 + 18917 = 18922
- 11 + 18911 = 18922
- 23 + 18899 = 18922
- 53 + 18869 = 18922
- 83 + 18839 = 18922
- 149 + 18773 = 18922
- 173 + 18749 = 18922
Showing the first eight; more decompositions exist.
