Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11220, here are decompositions:
- 7 + 11213 = 11220
- 23 + 11197 = 11220
- 43 + 11177 = 11220
- 47 + 11173 = 11220
- 59 + 11161 = 11220
- 61 + 11159 = 11220
- 71 + 11149 = 11220
- 89 + 11131 = 11220
Showing the first eight; more decompositions exist.
