Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6728, here are decompositions:
- 19 + 6709 = 6728
- 37 + 6691 = 6728
- 67 + 6661 = 6728
- 109 + 6619 = 6728
- 151 + 6577 = 6728
- 157 + 6571 = 6728
- 181 + 6547 = 6728
- 199 + 6529 = 6728
Showing the first eight; more decompositions exist.
