Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28756, here are decompositions:
- 3 + 28753 = 28756
- 5 + 28751 = 28756
- 53 + 28703 = 28756
- 59 + 28697 = 28756
- 107 + 28649 = 28756
- 113 + 28643 = 28756
- 137 + 28619 = 28756
- 149 + 28607 = 28756
Showing the first eight; more decompositions exist.
