Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22120, here are decompositions:
- 11 + 22109 = 22120
- 29 + 22091 = 22120
- 41 + 22079 = 22120
- 47 + 22073 = 22120
- 53 + 22067 = 22120
- 83 + 22037 = 22120
- 89 + 22031 = 22120
- 107 + 22013 = 22120
Showing the first eight; more decompositions exist.
