Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84158, here are decompositions:
- 31 + 84127 = 84158
- 37 + 84121 = 84158
- 97 + 84061 = 84158
- 367 + 83791 = 84158
- 397 + 83761 = 84158
- 421 + 83737 = 84158
- 439 + 83719 = 84158
- 457 + 83701 = 84158
Showing the first eight; more decompositions exist.
