Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11242, here are decompositions:
- 3 + 11239 = 11242
- 29 + 11213 = 11242
- 71 + 11171 = 11242
- 83 + 11159 = 11242
- 149 + 11093 = 11242
- 173 + 11069 = 11242
- 239 + 11003 = 11242
- 263 + 10979 = 11242
Showing the first eight; more decompositions exist.
