Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28758, here are decompositions:
- 5 + 28753 = 28758
- 7 + 28751 = 28758
- 29 + 28729 = 28758
- 47 + 28711 = 28758
- 61 + 28697 = 28758
- 71 + 28687 = 28758
- 89 + 28669 = 28758
- 97 + 28661 = 28758
Showing the first eight; more decompositions exist.
