Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28960, here are decompositions:
- 11 + 28949 = 28960
- 59 + 28901 = 28960
- 89 + 28871 = 28960
- 101 + 28859 = 28960
- 167 + 28793 = 28960
- 257 + 28703 = 28960
- 263 + 28697 = 28960
- 311 + 28649 = 28960
Showing the first eight; more decompositions exist.
