Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22028, here are decompositions:
- 31 + 21997 = 22028
- 37 + 21991 = 22028
- 67 + 21961 = 22028
- 157 + 21871 = 22028
- 211 + 21817 = 22028
- 229 + 21799 = 22028
- 241 + 21787 = 22028
- 271 + 21757 = 22028
Showing the first eight; more decompositions exist.
