Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11188, here are decompositions:
- 11 + 11177 = 11188
- 17 + 11171 = 11188
- 29 + 11159 = 11188
- 71 + 11117 = 11188
- 101 + 11087 = 11188
- 131 + 11057 = 11188
- 239 + 10949 = 11188
- 251 + 10937 = 11188
Showing the first eight; more decompositions exist.
