Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28746, here are decompositions:
- 17 + 28729 = 28746
- 23 + 28723 = 28746
- 43 + 28703 = 28746
- 59 + 28687 = 28746
- 83 + 28663 = 28746
- 89 + 28657 = 28746
- 97 + 28649 = 28746
- 103 + 28643 = 28746
Showing the first eight; more decompositions exist.
