Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84128, here are decompositions:
- 7 + 84121 = 84128
- 61 + 84067 = 84128
- 67 + 84061 = 84128
- 271 + 83857 = 84128
- 337 + 83791 = 84128
- 367 + 83761 = 84128
- 409 + 83719 = 84128
- 439 + 83689 = 84128
Showing the first eight; more decompositions exist.
