Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28732, here are decompositions:
- 3 + 28729 = 28732
- 29 + 28703 = 28732
- 71 + 28661 = 28732
- 83 + 28649 = 28732
- 89 + 28643 = 28732
- 101 + 28631 = 28732
- 113 + 28619 = 28732
- 173 + 28559 = 28732
Showing the first eight; more decompositions exist.
