Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84678, here are decompositions:
- 5 + 84673 = 84678
- 19 + 84659 = 84678
- 29 + 84649 = 84678
- 47 + 84631 = 84678
- 89 + 84589 = 84678
- 127 + 84551 = 84678
- 157 + 84521 = 84678
- 179 + 84499 = 84678
Showing the first eight; more decompositions exist.
