Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28082, here are decompositions:
- 13 + 28069 = 28082
- 31 + 28051 = 28082
- 139 + 27943 = 28082
- 163 + 27919 = 28082
- 181 + 27901 = 28082
- 199 + 27883 = 28082
- 283 + 27799 = 28082
- 331 + 27751 = 28082
Showing the first eight; more decompositions exist.
