Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28996, here are decompositions:
- 17 + 28979 = 28996
- 47 + 28949 = 28996
- 137 + 28859 = 28996
- 179 + 28817 = 28996
- 293 + 28703 = 28996
- 347 + 28649 = 28996
- 353 + 28643 = 28996
- 389 + 28607 = 28996
Showing the first eight; more decompositions exist.
