Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28770, here are decompositions:
- 11 + 28759 = 28770
- 17 + 28753 = 28770
- 19 + 28751 = 28770
- 41 + 28729 = 28770
- 47 + 28723 = 28770
- 59 + 28711 = 28770
- 67 + 28703 = 28770
- 73 + 28697 = 28770
Showing the first eight; more decompositions exist.
