Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84170, here are decompositions:
- 7 + 84163 = 84170
- 43 + 84127 = 84170
- 103 + 84067 = 84170
- 109 + 84061 = 84170
- 313 + 83857 = 84170
- 337 + 83833 = 84170
- 379 + 83791 = 84170
- 397 + 83773 = 84170
Showing the first eight; more decompositions exist.
