Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7844, here are decompositions:
- 3 + 7841 = 7844
- 103 + 7741 = 7844
- 127 + 7717 = 7844
- 157 + 7687 = 7844
- 163 + 7681 = 7844
- 223 + 7621 = 7844
- 241 + 7603 = 7844
- 271 + 7573 = 7844
Showing the first eight; more decompositions exist.
