Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84122, here are decompositions:
- 61 + 84061 = 84122
- 139 + 83983 = 84122
- 211 + 83911 = 84122
- 331 + 83791 = 84122
- 349 + 83773 = 84122
- 421 + 83701 = 84122
- 433 + 83689 = 84122
- 673 + 83449 = 84122
Showing the first eight; more decompositions exist.
