Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84642, here are decompositions:
- 11 + 84631 = 84642
- 13 + 84629 = 84642
- 53 + 84589 = 84642
- 83 + 84559 = 84642
- 109 + 84533 = 84642
- 139 + 84503 = 84642
- 179 + 84463 = 84642
- 193 + 84449 = 84642
Showing the first eight; more decompositions exist.
