Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22180, here are decompositions:
- 23 + 22157 = 22180
- 47 + 22133 = 22180
- 71 + 22109 = 22180
- 89 + 22091 = 22180
- 101 + 22079 = 22180
- 107 + 22073 = 22180
- 113 + 22067 = 22180
- 149 + 22031 = 22180
Showing the first eight; more decompositions exist.
