Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84728, here are decompositions:
- 31 + 84697 = 84728
- 37 + 84691 = 84728
- 79 + 84649 = 84728
- 97 + 84631 = 84728
- 139 + 84589 = 84728
- 229 + 84499 = 84728
- 271 + 84457 = 84728
- 307 + 84421 = 84728
Showing the first eight; more decompositions exist.
