Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104728, here are decompositions:
- 5 + 104723 = 104728
- 11 + 104717 = 104728
- 17 + 104711 = 104728
- 47 + 104681 = 104728
- 89 + 104639 = 104728
- 131 + 104597 = 104728
- 149 + 104579 = 104728
- 167 + 104561 = 104728
Showing the first eight; more decompositions exist.
