Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28022, here are decompositions:
- 3 + 28019 = 28022
- 61 + 27961 = 28022
- 79 + 27943 = 28022
- 103 + 27919 = 28022
- 139 + 27883 = 28022
- 199 + 27823 = 28022
- 223 + 27799 = 28022
- 229 + 27793 = 28022
Showing the first eight; more decompositions exist.
