Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27824, here are decompositions:
- 7 + 27817 = 27824
- 31 + 27793 = 27824
- 61 + 27763 = 27824
- 73 + 27751 = 27824
- 127 + 27697 = 27824
- 151 + 27673 = 27824
- 193 + 27631 = 27824
- 241 + 27583 = 27824
Showing the first eight; more decompositions exist.
