Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11208, here are decompositions:
- 11 + 11197 = 11208
- 31 + 11177 = 11208
- 37 + 11171 = 11208
- 47 + 11161 = 11208
- 59 + 11149 = 11208
- 89 + 11119 = 11208
- 137 + 11071 = 11208
- 139 + 11069 = 11208
Showing the first eight; more decompositions exist.
