Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12828, here are decompositions:
- 5 + 12823 = 12828
- 7 + 12821 = 12828
- 19 + 12809 = 12828
- 29 + 12799 = 12828
- 37 + 12791 = 12828
- 47 + 12781 = 12828
- 71 + 12757 = 12828
- 89 + 12739 = 12828
Showing the first eight; more decompositions exist.
