Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84212, here are decompositions:
- 13 + 84199 = 84212
- 31 + 84181 = 84212
- 151 + 84061 = 84212
- 229 + 83983 = 84212
- 379 + 83833 = 84212
- 421 + 83791 = 84212
- 439 + 83773 = 84212
- 523 + 83689 = 84212
Showing the first eight; more decompositions exist.
