Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11180, here are decompositions:
- 3 + 11177 = 11180
- 7 + 11173 = 11180
- 19 + 11161 = 11180
- 31 + 11149 = 11180
- 61 + 11119 = 11180
- 67 + 11113 = 11180
- 97 + 11083 = 11180
- 109 + 11071 = 11180
Showing the first eight; more decompositions exist.
