Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11212, here are decompositions:
- 41 + 11171 = 11212
- 53 + 11159 = 11212
- 233 + 10979 = 11212
- 239 + 10973 = 11212
- 263 + 10949 = 11212
- 353 + 10859 = 11212
- 359 + 10853 = 11212
- 431 + 10781 = 11212
Showing the first eight; more decompositions exist.
