Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11158, here are decompositions:
- 41 + 11117 = 11158
- 71 + 11087 = 11158
- 89 + 11069 = 11158
- 101 + 11057 = 11158
- 131 + 11027 = 11158
- 179 + 10979 = 11158
- 269 + 10889 = 11158
- 311 + 10847 = 11158
Showing the first eight; more decompositions exist.
