Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82122, here are decompositions:
- 71 + 82051 = 82122
- 83 + 82039 = 82122
- 101 + 82021 = 82122
- 109 + 82013 = 82122
- 113 + 82009 = 82122
- 149 + 81973 = 82122
- 151 + 81971 = 82122
- 179 + 81943 = 82122
Showing the first eight; more decompositions exist.
