Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11216, here are decompositions:
- 3 + 11213 = 11216
- 19 + 11197 = 11216
- 43 + 11173 = 11216
- 67 + 11149 = 11216
- 97 + 11119 = 11216
- 103 + 11113 = 11216
- 157 + 11059 = 11216
- 223 + 10993 = 11216
Showing the first eight; more decompositions exist.
