Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11218, here are decompositions:
- 5 + 11213 = 11218
- 41 + 11177 = 11218
- 47 + 11171 = 11218
- 59 + 11159 = 11218
- 101 + 11117 = 11218
- 131 + 11087 = 11218
- 149 + 11069 = 11218
- 191 + 11027 = 11218
Showing the first eight; more decompositions exist.
